1.	Why AM is used for broadcasting?(a) More immune to noise(b) Less transmitting power is required(c) It has high fidelity(d) Avoids Receivers ComplexityThe question was posed to me in semester exam.Origin of the question is Single Tone Modulation in portion Amplitude Modulation of Analog Communications
Answer» The correct answer is (d) Avoids Receivers Complexity For explanation: AM detectors are GENERALLY, square law demodulators or envelope detectors at the receiver. As AM detectors at the receiver end are simple CIRCUITS and AVOID any KIND of complex structure, THEREFORE, AM used for broadcasting.
