Q. The baseband signal π(π‘) shown in the figure is phase-modulated to generate the PM signal π(π‘) = cos(2ππππ‘ + π π(π‘)). The time π‘ on the x-axis in the figure is in milliseconds. If the carrier frequency is ππ = 50 kHz and π = 10π, then the ratio of the minimum instantaneous frequency (in kHz) to the maximum instantaneous frequency (in kHz) isΒ (rounded off to 2 decimal places).
Ans: 0.74 – 0.76
