1.	A sensitive and selective receiver can be made using only amplifiers, selective filters, and a demodulator.(a) True(b) FalseI had been asked this question during an interview.I'd like to ask this question from Communication Receivers in portion Radio Transmitters, Communication Receivers, Multiplexing and Demultiplexing of Avionics
Answer» The CORRECT answer is (a) True The explanation: A sensitive and selective receiver can be made using only AMPLIFIERS, selective filters and a demodulator. This is called a tuned radio frequency or TRF receiver. EARLY radios used this design. However, such a receiver does not USUALLY deliver the kind of performance expected in modern COMMUNICATIONS applications.
