Explanation / Answer

Qu:what is multiplexing? differentiate between frequency and time division multiplexing.

Multiplexing:Multiplexing is the process of allow several signals beginning diverse source to split frequent communication channel. To is a solitary direct be second-hand by unlike signal source to send their signal.

There are many types of multiplexing some of them as:
(a) TDM (Time Division Multiplexing
(b) FDM (Frequency Division Multiplexing)
(c) WDM (Wavelength Division Multiplexing)
(d) CDM (Code Division Multiplexing

FDM

Suppose there are 4 indication sources, then every signal source resolve be allowed to use line for a period t. one time all signal sources broadcast for period t, the primary one once more get chance and consequently on.

. At receiving conclusion signal are demodulated. (i.e. translated back to innovative frequency).

TDM

FDM

TDM signals are seperated in time domain. Fdm signals are separated domain. signal from various sources be allowable to flow from side to surface the ordinary line one at a time for fixed time. Signal from each basis is modulate to different occurrence as a result that the incidence spectrum after modulation will not partly cover
