On radiation (sending out) an AM modulated signal, the total radiated power is due to energy carried by `omega_c, omega_c - omega_m and omega_c + omega_m`. Suggest ways to minimise cost of radiation without compromising on information.

Text Solution

Verified by Experts

In amplitude modulated signal, out of `(omega_c - omega_m)` and `(omega_c + omega_m)` only `(omega_c +omega_m)` and `(omega_c - omega_m)` contain
infromation. Hence cost can be reduced by tansmitting `(omega_c + omega_m), (omega_c - omega_m)` or both `(omega_c + omegam)` and `(omega_c - omega_m)`.

The efficient transmission of signals is achieved by superimposing electrical audio signals on a high frequency carrier wave (the process is known as modulation). When the amplitude of high frequency carrier wave is changed in accordance with the intensity of modulating signal, it is called amplitude modulation. The extent to which the amplitude of carrier wave is changed by the signal is described by modulation factor. It is given as m="Amplitude change of carrier wave"/"Amplitude of unmodulated carrier wave" Let a carrier wave is represented by V_c=V_c cos omega_ct Let the modulation factor be m, the maximum change in amplitude of carrier wave is mV_c So, modulating signal can be represented as v_m=mV_c cosomega_mt So, the amplitude of modulated wave is =V_c+mV_c cosomega_m t Using this value, the instantaneous voltage of modulated wave is E=V_c cos omega_c t+ (mV_c)/2 cos (omega_c+omega_m)t + (mV_c)/2 cos (omega_c-omega_m ) t The above wave contains three frequencies namely, f_c, f_c+f_m and f_c-f_m .
