In a TDD one channel is sufficient for transmission.(a) True(b) FalseThe question was asked in quiz.My query is from Pulse Code Modulation topic in division Radio Transmitters, Communication Receivers, Multiplexing and Demultiplexing of Avionics

Answer»

Correct answer is (a) True

Easy explanation: Time-division duplexing (TDD) means that signals are transmitted simultaneously on a single CHANNEL by interleaving them in different time slots. Each time slot may contain one data word, such as 1 byte from an A/D CONVERTER or a D/A converter. As long as the serial data RATE is high ENOUGH, a user will never know the difference. The primary benefit of TDD is that only one channel is needed. It saves spectrum space and cost.
