engineering recuitment GATE IN Test Series 2023-24 Mock Test Communication Systems Angle Modulation Frequency Modulation
Two sinusoidal signals of same amplitude & frequencies 10 kHz & 10.1 kHz are added together. The combined signal is given to an ideal frequency detector. The output of the detector is
1
0.1 kHz sinusoid
2
20.1 kHz sinusoid
3
a linear function of time
4
a constant
