A modulated signal is represented as
x(1) = 6 sin 1250 t + sin `10^(8)` t then the
mudulating index is

A wave is represented as e=10 sin (10^(8)t+6 sin 1250t) then the modulating index is

An amplitude modulated wave is represented by C_m = 10(1+ 0.2 sin 12560 t ) sin (1.11 x 10^4 t) V . The modulating frequency in KHz will be

The equation of an FM signal is e = 6 sin (10^(6) t + 4 sin 10^(3) t ) . Then, the modulating frequency is

The equation of an FM signal is e = 6 sin (10^(6) t + 4 sin 10^(3) t ) . Then, the modulating frequency is

In an amplitude modulator circuit, the carrier wave is given by, C(t) =4 sin (20000 pi t) while modulating signal is given by, m(t) =2 sin (2000 pi t) . The values of modulation index and lower side band frequency are :
