Assignment 1:
Crosstalk a disturbance caused by the electric or magnetic fields of one telecommunication signal affecting a signal in an adjacent circuit
Waveguides an electromagnetic feed line used in microwave communications, broadcasting, and radar installations
FTTH is the installation and use of optical fiber from a central point directly to individual buildings such as residences, apartment buildings and businesses
Simplex a communications mode in which only one signal is transmitted, and it always goes in the same direction
Half-Duplex data can be transmitted in both directions on a signal carrier, but not at the same time.
Full-Duplex data can be transmitted in both directions on a signal carrier, at the same time. 1. Photodiode a semiconductor diode that, when exposed to light, generates a potential difference or changes its electrical resistance
Amplitude Modulation the transmission of data by varying the amplitude of the individual pulses in a regularly timed sequence of electrical or electromagnetic pulses.
Analog Transmission a base carrier's alternating current frequency is modified in some way, such as by amplifying the strength of the signal or varying the frequency, in order to add information to the signal
Digital Transmission the physical transfer of data over a point-to-point or point-to-multipoint communication channel.
Sample Rate the number of samples of a sound that are taken per second to represent the event digitally.
Electromagnetic Wave sometimes referred to as an EM field, is generated when charged particles, such as electrons, are accelerated
Refraction light, radio waves, etc., being deflected in passing obliquely through the interface between one medium and another or through a medium of varying density.
Medium a thirdparty or element through which a message is communicated
Total Internal a
