Modulation is the process of changing the form of signal received (from digital to analog), while demodulation is the process of extracting information from the signal that has been received and modulated (by conversion from analog to digital). This is important because telephone lines are unable to carry digital signals, while computers can only understand digital signals which are made up of 1s and 0s. A DSL modem requires a network access phone number and logon

different thresholds. Then the data from the accelerometer need to be transferred to the microcontroller which is used to process the data. The microcontroller which we have selected to do the processing of the data is MKL25Z32VFM4 which is ARM® Cortex™-M0+ processor. This is best suited for the processing of the accelerometer data. There are different types of protocols that can be

size and cost compared to a design that uses a separate microprocessor, memory, and input/output devices, microcontrollers make it economical to digitally control even more devices and processes. Mixed signal microcontrollers are common, integrating analog components needed to control non-digital electronic systems. Some microcontrollers may use four-bit words and operate at clock rate frequencies as low as 4 kHz, for low power consumption (milliwatts or microwatts). They will generally have the

The advent of digital computation and the “discovery” of fast Fourier Transform (FFT) algorithm in the late 1950s revolutionized the field of signal processing, and allowed for the first time practical processing and meaningful interpretation of a host of signals of exceptional human and industrial importance. • The frequency domain refers to the plane of the two dimensional discrete Fourier transform of an image. • The purpose of the Fourier transform is to represent a signal as a linear combination

This report introduces and motivates the use of hybrid robust feature extraction techniques for continuous speech recognition for Bengali Numerical digits system. The speech recognizers use a parametric form of a signal to get the most important distinguishable features of speech signal for recognition task. In this paper Linear predictive coding (LPC), Mel-frequency cepstral coefficients (MFCC), Perceptual linear prediction coefficients (PLP) along with a hybrid feature Bark Frequency Cepstral Coefficients
