A carrier wave of peak voltage 14 V is used for transmitting a message signal. The peak voltage of modulating signal given to achieve a modulation index of 80% will be :

An amplitude modulated wave is as shown in figure. Calculate (i) the percentage modulation, (ii) peak carrier voltage and , (iii) peak value of information voltage.

An amplitude modulated wave is as shown in figure. Calculate (i) the percentage modulation, (ii) peak carrier voltage and , (iii) peak value of information voltage.

the figure represents a voltage regulator circuit using a zener diode. The breakdown voltage of the zener diode is 6 V and the load resistance is R_(L)=4kOmega the series resistance of the circuit is R_(i)=1kOMega . if the battery voltage V_(B) varies from 8 V to 16 V, what are the minimum and maximum values of the currect through Zener diode?

if the maximum and minimum voltage of AM wave are V_(max) and V_(min) , respectively then modulation factor

The antenna current of an AM transmitter is 8A when only the carrier is sent but increases to 8.96A when the carrier is modulated sinusoidally . The percentage modulation is

The maximum peak to peak voltage of an AM wave is 24mV and the minimum peak to peak voltage is 8mV. The modulation factor is equal to

A: If the amplitude of a message signal is half of the amplitude of the carrier wave, then the index of modulation is 50%. R: In amplitude modulation the amplitude of the carrier wave varies in accordance with the signal voltage of the message signal.
