The technique that makes possible the task of listening and talking in communication system is called ____

A	Simplexing
B	Duplexing
C	Modulating
D	Multiple access technique

Explanation:

Detailed explanation-1: -Explanation: In conventional telephone systems, it is possible to talk and listen simultaneously. This effect is called duplexing and is generally required in wireless telephone systems.

Detailed explanation-2: -Frequency-division duplexing (FDD) is a method for establishing a full-duplex communications link that uses two different radio frequencies for transmitter and receiver operation. FDD operation normally assigns the transmitter and receiver to different communication channels.

Detailed explanation-3: -Explanation: Pulse stuffing is a technique that can be a solution to the problem of synchronizing data sources. In pulse stuffing, the outgoing data rate is higher than sum of incoming rates.

Detailed explanation-4: -In FDMA, all users share the satellite transponder or frequency channel simultaneously but each user transmits at single frequency. FDMA can be used with both analog and digital signal but it generally used with analog signal. FDMA requires high-performing filters in the radio hardware, in contrast to TDMA and CDMA.
