An angle modulated signal is given as \(v\left( t \right) = 5\cos \left[ {10^62\pi t + 5\sin \left( {{{10}^3} \times 2\pi t} \right)} \right]\). The maximum phase deviation and frequency deviations are

A modulated signal is given

x(t) = 10 cos (2π × 10⁵ t) + 6 cos (2π × 10³t)cos (2π × 10⁵t)

This signal is to be detected by a linear diode. The most suitable value of resistance if the capacitor is of 100 pF is

A FM is fed with a message signal m(t) = A_M cos(2π × 1.6 × 10³)t. The value of AM is gradually increased from 0 and it is found that at AM = 2V the carrier component goes to zero for the first time. Determine at what value of AM the carrier component will again go to zero ______.
