Use of IS, AM, ARE

The power of a AM transmitter is 100 W. If the modulation index is 0.5 and the transmission is having signal side band, the percentage of useful power is

Assertion: FM broadcat is better than AM broadcast. Reason: Noice change is maximum is amplitude of AM waves.

A message signal of freuency omega_(m) is superposed on a carrier wave of frequency omega_(c) to get an amplititude modulated wave (AM). The frequency of the AM wave will be

A message signal of freuency omega_(m) is superposed on a carrier wave of frequency omega_(c) to get an amplititude modulated wave (AM). The frequency of the AM wave will be

A message signal of freuency omega_(m) is superposed on a carrier wave of frequency omega_(c) to get an amplititude modulated wave (AM). The frequency of the AM wave will be

Given two numbers a and b. Let A denote the single A.M. and S denote the sum of n A.M.'s between a and b, then S//A depends on

A message signal of freuency omega_(m) is superposed on a carrier wave of frequency omega_(c) to get an amplititude modulated wave (AM). The frequency of the AM wave will be

In a DeltaABC, a =1 and the perrimeter is six times the AM of the since of the angles.The measure of angle A is

STATEMENT-1. The transmission using FM is more efficient as compared to AM STATEMENT-2: In FM, amplitude and therefore power handled is constant

Which of the following is an advantage of FM over AM?
