An audio signal consists of two distinct sound. One a human speech signal in the frequency band of `200Hz` to `2700Hz`, while the other is a high frequency music signal in the frequency band of `10200Hz` to `15200Hz`. The ratio of the AM signal together to the AM signal band width required to send just the human speech is:

Two audio speakers are kept some distance apart and are driven by the same amplifier system. A person is sitting at a place 6.0 m from one of the speakers and 6.4 m from the other. If the sound signal is continuously varied from 500 Hz to 5000 Hz, what are the frequencies for which there is a destructive interference at the place of the listener? Speed of sound in air = 320 ms^-1

A train standing at the outer signal of a railway station blows a whistle of frequency 400Hz in still air. (i) What is the frequency of the whistle for a platform observer when the train (a) approaches the platform with a speed of 10 ms^(-1) . (b) recedes from the platform with a speed of 10ms^(-1) ? (ii) What is the speed of sound in each case? The speed of sound in still air can be taken as 340ms^(-1) .

Two radio stations broadcast their programmes at the same amplitude A and at slightly different frequencies omega_(1) and omega_(2) respectively, where omega_(1) - omega_(2) = 10^(3) Hz . A detector receives the signals from the two stations simultaneously, it can only detect signals of intensity ge 2A^(2) . (i) Find the time interval between successive maxima of the intensity of the signal received by the detector. (ii) Find the time for which the detector remains idle in each cycle of the intensity of the signal.

A bat moving at 1 0 ms^(-1) towards a wall sends a sound signal of 8000 Hz towards it. On reflection it hears a sound of frequency f. The value of g in Hz is close to (speed to sound = 320 ms^(-1) ) :-
