"Examples of such channels are copper wires, optical fibers, wireless communication using radio spectrum, storage media, and computer buses."
"The data are represented as an electromagnetic signal, such as an electrical voltage, radiowave, microwave, or infrared signal."
"Analog transmission is a method of conveying voice, data, image, signal, or video information using a continuous signal which varies in amplitude, phase, or some other property in proportion to that of a variable."
"The messages are either represented by a sequence of pulses by means of a line code (baseband transmission), or by a limited set of continuously varying waveforms (passband transmission)."
"The passband modulation and corresponding demodulation is carried out by modem equipment."
"According to the most common definition of digital signal, both baseband and passband signals representing bit-streams are considered as digital transmission."
"An alternative definition only considers the baseband signal as digital, and passband transmission of digital data as a form of digital-to-analog conversion."
"Digital messages originating from a data source, for example, a computer or a keyboard."
"This source coding and decoding is carried out by codec equipment."
"Analog signals such as a phone call or a video signal are digitized into a bit-stream, for example, using pulse-code modulation or more advanced source coding schemes."
"To receive data transmitted over a communication channel."
"Represented by a sequence of pulses by means of a line code."
"Using a limited set of continuously varying waveforms."
"Carrying out passband modulation and corresponding demodulation."
"Copper wires, optical fibers, wireless communication using radio spectrum, storage media, and computer buses."
"Transferred as a digital bitstream or a digitized analog signal."
"To perform source coding and decoding."
"Amplitude, phase, or some other property."
"Such as an electrical voltage, radiowave, microwave, or infrared signal."
