=>kφ = -0.13. 6. When does a digital phase detector can be used, where fo->output frequency, fs->input frequency.
A. Both fo & fs signals should be square wave
B. fo should be square wave & fs can be any non-sinusoidal wave
C. fs should be square wave & fo can be any non-sinusoidal wave
D. Both fo & fs can be any non-sinusoidal wave

Explanation: The XOR gate produces high output when only one of the input signal fo or fs is high. So, to detect high or low value of waveform, square waves are used. 7. The maximum dc output voltage in digital phase detector occurs
