`C(t)` and `m(t)` are used to generate an `AM` signal. The modulation indes of generated `AM` signal is `0.5`. Then the quantity `(P_("Total "SB))/(P_("Carrier"))=`

What is the modulation index if an audio signal of amplitude one half of the carrier amplitude is used in AM?

" The total power content of an AM signal is "3000" w.For "100%" modulation,the power of CW and that of each side band are "

(A): A FM signal is less susceptible to noise than an AM signal. (B) : In FM transmission, the message signal is in the form of frequency variations of carrier waves. During modulation process, the noise gets amplitude modulated.

The total power content of an AM signal is 3000 w. For 100% modulation, the power of CW and that of each side band are,

A signal Acosomegat is transmitted using v_(0) sinomega_(0)t modulated (AM) signal is:

Let m(t)=cos(4pixx10^(3)t) and C(t)=5cos(2pixx10^(6)t) are the message and carrier signals modulation index is 0.5 . What is the efficency achieved?

In an amplitude modulator circuit the carrier wave is given by C(t) = 4 sin(2 pi × 10^7 t) while modulating signal is given by m(t) = 2 sin(2 pi × 10^5 t) . Then the bandwidth of the broadcast signal will be
