1.	When an antenna radiates more energy in one direction than in other directions, it is called ________(a) selectivity(b) directivity(c) active antenna(d) resonanceI had been asked this question in quiz.This intriguing question originated from Time Division Multiplexing topic in section Multiplexing & Sampling of Bandpass Signal of Analog Communications
Answer» Correct option is (b) DIRECTIVITY The explanation: When an ANTENNA radiates more energy in one direction than in other directions is called directivity. An antenna that radiates equally in all directions has effectively zero DIRECTIONALITY, and the directivity of this type of antenna should be 1 (or 0dB).
