1.	The ability to pick up week signals by a receiver is called _________(a) Gain(b) Amplification(c) Sensitivity(d) SelectivityI had been asked this question in examination.My question is taken from Communication Receivers in section Radio Transmitters, Communication Receivers, Multiplexing and Demultiplexing of Avionics
Answer» RIGHT ANSWER is (c) Sensitivity Explanation: A communication receiver’s sensitivity, or ability to pick up weak signals, is mainly a function of OVERALL gain, the factor by which an input signal is multiplied to PRODUCE the output signal. In general, the HIGHER the gain of a receiver, the better its sensitivity.
