   What is modulation in a communication channel?

   • To transmit signals with frequencies required by the communication channel, the transmitter centers the spectrum of the information signal at the transmission frequency. This process of shifting the frequency spectrum of a signal is called modulation. As an example human voice spans a 4 kHz range or bandwidth, and is centered at 0 kHz.

   What is a communication system model?

   • Communication system is a system model describes a communication exchanges between two stations, transmitter and receiver. Signals or information’s passes from source to distention through what is called channel, which represents a way that signal use it to move from source toward destination.

   What is pulse coded modulation?

   • In a strict sense, “pulse coded modulation” is in fact a (crude) source coding technique (i .e , method of digitally representing analog information). There are more advanced source coding (compression) techniques in information theory. Coding The bits of PCM, DPCM etc need to be converted into some electrical signals.
