Suppose that the phase-modulated signal of Problem has an arbitrary value for the maximum phase deviation
Question:
Suppose that the phase-modulated signal of Problem has an arbitrary value for the maximum phase deviation βp. This modulated signal is applied to an ideal band-pass filter with mid-band frequency ƒc and a pass-band extending from ƒc – 1.5ƒm to ƒc + 1.5ƒm. Determine the envelope, phase, and instantaneous frequency of the modulated signal at the filter output as functions of time.

I am graduated in Physics in 2018, from KIRORIMAL COLLEGE, University of Delhi. Now I am persuing Master's degree in physics. I like to do physics problems. I have experience of 1 year in tutoring. I think Physics is the only subject where you understand things,how they are happening . In physics you learn Maths and apply it. So I would like to join your platform to solve many Physics problems.
