1.	FDM is an analog multiplexing technique used to combines ________(a) analog signals(b) digital signals(c) both analog and digital signals(d) alternatively passes analog and digital signalsI got this question during an interview for a job.This interesting question is from FDM System topic in portion Amplitude Modulation of Analog Communications
Answer» Right choice is (a) analog signals The explanation: Frequency Division Multiplexing (FDM) is a networking TECHNIQUE in which MULTIPLE data signals are combined for simultaneous transmission VIA a shared communication medium. FDM uses a carrier SIGNAL at a discrete frequency for each data stream and then combines many modulated signals. FDM is used to multiplex multiple analog signals. FDM is APPLIED when the bandwidth of the link is greater than the combined bandwidth of signals to be transmitted.
