...1) Crosstalk (XT) is any phenomenon by which a signal transmitted on one circuit or channel of a transmission system creates an undesired effect in another circuit or channel. 2) Waveguide is a structure that guides waves, such as electromagnetic waves or sound waves. There are different types of waveguides for each type of wave. The original and most common[1] meaning is a hollow conductive metal pipe used to carry high frequency radio waves, particularly microwaves. 3) Fiber to the x (FTTx) is a generic term for any broadband network architecture using optical Fiber to replace all or part of the usual metal local loop used for last mile telecommunications. 4) Simplex communication refers to communication that occurs in one direction only. 5) A half-duplex (HDX) system provides communication in both directions, but only one direction at a time (not simultaneously). 6) A full-duplex (FDX), or sometimes double-duplex system, allows communication in both directions, and, unlike half-duplex, allows this to happen simultaneously. 7) Photodiode is a type of photo detector capable of converting light into either current or voltage, depending upon the mode of operation. 8) Amplitude modulation (AM) is a technique used in electronic communication, most commonly for transmitting information via a radio carrier wave. 9) Analog (or analogue) transmission is a transmission method of conveying voice, data, image, signal or video information using...

...investigation which comprises of testing three operational amplifier circuits with AC signals. The three types of circuit include the integrator, the AC inverting amplifier and the AC non-inverting amplifier circuit. The integrator circuit was tested with a square-wave and a sinusoidal wave input signal at 1kHz frequency. The results showed that the square-wave input signal produced a triangular wave output whereas the sinusoidal input produced a sinusoidal output signal with a positive 90 degree phase shift. Both output signals were showed to be the integral of their relative input signals. The output voltage gain of the AC inverting and the AC non-inverting amplifier circuits were tested with a frequency range of 100Hz to 10kHz. The results were plotted on a logarithmic scaled graph which showed that both amplifiers acted like high-pass filters, each amplifier achieving its maximum gain set by the specification at higher frequencies nearer to 10kHz. The only difference between the two op-amps was that the AC inverting amplifier achieved negative gain in comparison to the positive gain achieved by the AC non-inverting amplifier. For further investigation, the frequency was increased above 10kHz for the AC inverting amplifier circuit which showed a linear fall in gain, which was explained by the theory of slew rate limitation. In conclusion, the three operational amplifiers operated as expected. Table of Contents ABSTRACT 1 1. INTRODUCTION 4 2. THEORY 4 2.1. Open-loop...

...Women and Beauty Magazines by Christine Hetcher Beauty magazines, such as Cosmopolitan, Glamour, and Marie Claire, are widely read by women throughout America . What do women actually think of these magazines? Do they feel the magazines are helpful, degrading, or simply something to read? This paper is a survey interview to determine what women in their late teens and early twenties think about beauty magazines in Americatoday. The purpose of this study is to determine whether women like or dislike beauty magazines, why they like or dislike them, and how frequently women read beauty magazines. Background This section reviews the previous studies conducted on the effects of women’s magazines. Magazines specifically written for women have been in circulation for over sixty years, discussing whatever issues were relevant to women at the time (Moskowitz, 1996). Some of the earlier magazines focused on a war-time rebellion of feminism. Moskowitz (1996) conducted a study about the effects of war-time magazines and said, “Women’s magazines of the Cold War era remain symbols of antifeminism” (p. 66). Moskowitz (1996) found that many women liked the articles because many magazines discussed important issues to them, such as stress, emotionalism, and feminism (p.66). Moskowitz (1996) said, “recognition of emotional tension was common for women’s magazines” (p.67). This recognition “presented a whole new genre of articles that gave housewives the freedom...

...coverage. The mission of the UH72A in the Security and Support battalions is heavily loaded with civil support. Technology has advanced considerably since the production of the current communications package. Law enforcement and federal agencies have been on top of the technology shift including radios that have proprietary software and proprietary encoding. Observation 1: Communications Interoperability of the UH72A due to outdated communications and the array of commercial equipment available to the civil community. Discussion: Currently in the UH72A we have 2 Garmin VHF radios, 1 ARC231 FM/VHF/UHF capable of single channel/frequency hopping/Havquick, and 2 Colbahm radios of single channel FM/VHF/UHF with tone codes (squelch codes). That package worked accordingly on a year 2005 level. Since that time there have been major development in frequency discretion and encoding. The manufacturer of the communication equipment elects to develop software and coding that is discrete to that manufacturer. The discrete coding and software poses an intercommunication issues between other radios on the market and in the field. This typically happens with the federal agencies that seem to acquire more funds for technology than state and local agencies. Recommendation: Since there are so many different manufacturers producing different software and encoding it is not feasible to install all necessary radios to cover the spectrum. One solution is one piece of equipment that will be...

...The Basic Parts The Basic Parts There are just five basic parts in a radio frequency communication system. These are: * Antenna * Amplifier * Filter * Mixer * Source These five parts are then put together to do one of two basic functions: transmit or receive. The name of the resulting device is a radio. The radio also may go by many other names based on marketing considerations or its specific role in the wireless network. A radio is used to send and receive a signal that flows through the air as a series of electromagnetic waves. Radios can take on many different forms. As such, it is not always easy to identify them. When transmitting or receiving, the goal is to produce a perfect sine wave, of the exact size required, at only one frequency. A block diagram of the basic parts looks like the following. For a transmitter: This diagram shows a conceptual layout of a typical transmitter. Included in it are six elements. They are, in order: source, amplifier, source, mixer, filter, high-power amplifier, and antenna. For a transmitter, the signal is generated by the source. The mixer changes the frequency of the signal. The filter removes undesired frequencies. The amplifier increases the signal. The antenna transforms the electrical current into a radio wave. The other amplifier provides the electrical signal. It also feeds into the mixer. For a receiver: This diagram shows a conceptual layout of a typical receiver. Included in it are seven...

... wavelength length of a wave c. frequency number of waves per second (Hz) d. period how long a wave lasts when it arrives at a fixed point (measured in seconds) 3. What are radio waves? An electromagnetic wave of a frequency used for long distant communication. 4. Explain the difference between a transverse wave and a longitudinal wave, and give examples of each. In a longitudinal wave, the vibration travels in the same direction that wave travels. Examples of longitudinal waves include: Sound, p-waves (earthquakes) In a transverse wave, the vibration direction is perpendicular to direction that wave travels. Examples include: Light/electromagnetic, (radio, microwave, xray, etc.), water waves, swaves (earthquakes). The major difference between longitudinal and transverse waves is their direction. Longitudinal waves move left to right while transverse waves move up and down. 5. Compare and contrast: light waves vs. sound waves Light waves are transverse and sound waves are longitudinal. Light waves can travel through a vacuum but sound waves cannot. Speed of light is nearly 300 million m/s while sound has a speed of about 340 m/s. 6. What changes the pitch of sound? The frequency of vibration. Faster vibration would cause a higher pitch while slower vibration would cause a lower pitch. 7. Explain how different factors affect the speed of sound? Speed of sound depends on factors such as altitude, humidity...

...maximum frequency that would not be aliased was the Nyquist frequency, which was 5000 Hz. In addition to that, the amplitude of the loud voice was higher than the amplitude of the low voice. The number of bits calculated based on the quantization was equal to 9.97 bits. The high cutoff and the low cutoff which are 110 Hz and 1100 Hz, were used to show the Fast Fourier Transform of the filtered voices, which results in producing better voice of the recording. Based on the FFT graphs, the amplitude of the 440 Hz was the highest at the same peak, and that is why the sound was directly clear, and that proves that the played sound was with the frequency of 440 Hz. For the low and loud frequency, the graph showed the background noise recorded with the voice signal. The use of the decimating factor is that it will resample the recorded voice signal at a lower sampling frequency. Therefore, by changing the value of the decimating factor, the between 1 to 8, the sounds became more clear and recognizable. That is because the decimating factor, decrease the sample rate and increase the frequency of the voice signal in order to avoid the signal to be aliased. Based on research, the...

...patterns found in multi-year planetary orbits and those found when studying Cymatics but also the correlation of those to the orbital patterns of electrons around their nucleus on the atomic level. You may be asking yourself what exactly is Cymatics, or even perhaps what is this lunatic talking about? To begin to answer these questions I will describe Cymatics first. Cymatics is the study of visible sound and vibration, a subset of modal phenomena. Typically the surface of a plate, diaphragm, or membrane is vibrated, and regions of maximum and minimum displacement are made visible in a thin coating of particles, paste, or liquid. Different patterns emerge in the exitatory medium depending on the geometry of the plate and the driving frequency. (Hans, 2001) In short it is making shapes with sounds. Below I have included a picture of some of the geometric patterns observed through Cymatics (see figure 1) as well as pictures of electron orbits (figure 2 and 3 ) and multi-year orbital patterns of some planets. (figures 4, 5, 6, and 7) As you can see upon first examination of...

...1 Learning Fingerprint Reconstruction: From Minutiae to Image Kai Cao and Anil K. Jain, Fellow, IEEE Abstract—The set of minutia points is considered to be the most distinctive feature for fingerprint representation and is widely used in fingerprint matching. It was believed that the minutiae set does not contain sufficient information to reconstruct the original fingerprint image from which minutiae were extracted. However, recent studies have shown that it is indeed possible to reconstruct fingerprint images from their minutiae representations. Reconstruction techniques demonstrate the need for securing fingerprint templates, improve the template interoperability and improve fingerprint synthesis. But, there is still a large gap between the matching performance obtained from original fingerprint images and their corresponding reconstructed fingerprint images. In this paper, the prior knowledge about fingerprint ridge structures is encoded in terms of orientation patch and continuous phase patch dictionaries to improve the fingerprint reconstruction. The orientation patch dictionary is used to reconstruct the orientation field from minutiae, while the continuous phase patch dictionary is used to reconstruct the ridge pattern. Experimental results on three public domain databases (FVC2002 DB1 A, FVC2002 DB2 A and NIST SD4) demonstrate that the proposed reconstruction algorithm outperforms the stateof-the-art reconstruction algorithms in terms of both i) spurious ...
