Q1:

Which of the following is correct (FDM means Frequency Division Multiplexing and TDM means Time Division Multiplexing)?

A FDM requires lower bandwidth but TDM has more noise immunity

B FDM has more noise immunity and requires lower bandwidth than TDM

C FDM requires channel synchronization while TDM has more noise immunity

D FDM requires more multiplexing while TDM requires band pass filter

ANS:C - FDM requires channel synchronization while TDM has more noise immunity

As per my knowledge; TDM requires channel synchronization and FDM need large Bandwidth(180KHZ).
