The amplitude of an AF signal is 10 and that of the carrier wave is 50 Percentagemodulation is

If A_m and A_c are the amplitudes of modulating signal and carrier wave respectively, then modulation index is given by

Why is the amplitude of modulating signal kept less than the amplitude of carrier wave ?

Both amplitude modulation (AM) and frequency modulation (FM) are used for radio broadcasting. The amplitude of the high frequency carrier wave is varied or modulated in accordance with the variations in the amplitude of the audio signals that are to be transmitted, in te process of amplitude modulation in frequency modulation te amplitude of the carrier remains constant but its frequency is varied inn accordance withh the audio signal. Reception with AM signals is in general is affected by interference of various kinds ad elaborated equipment is required for FM broadcast. A radio frequency carrier wave can be modulated using a-

An audio signal of amplitude one half the carrier amplitude is employed in amplitude modulation. What is the modulation index?

In an amplitude modulation with modulation index 0.5 the ratio of the carrier wave to that of side band in the modulated wave is

An audio signal of amplitude 0.1 V is used is used in amplitude modulation of a carrier wave of amplitude 0.2 V. Calculate the modulation index.

In an amplitude modulation, amplitude of carrier wave is 250mV and amplitude of message signal is 150mV. If A_(MAX)/A_(MIN) = X/50 then find x...
