If modulation index, $$\mu=\frac{1}{2}$$ and $$V_m=2$$, then $$V_C$$ is

Assertion : In ionospheric reflection, phase change does not occur with the radio wave. Reason : The ionosphere reflection is similar to the total int...

Assertion : Amplitude modulation shows more interference than frequency modulation with noise. Reason : Interference is function of amplitude of modul...

A diode detector is used to detect and amplitude modulated wave of 60% modulation by using a condenser of capacity 250 pF in parallel with a load resi...
