Thread: Angle modulating signal mathematics

Given an angle modulated signal is:

Xc(t)=10cos[2 pi 10^6 pi t + 0.1sin(pi 10^3 t)]

1. Find m(t) if Xc(t) is FM with Kf = 10 pi

2. Find m(t) if Xc(t) is PM with Kp = 10

Unfamiliar notation.

I believe the notation is:
Kf is the constant "K" of Frequency "f", while:
Kp is the constnat "K" of the Phase "p"

Remember it is "angle modulated"..

Oops.
If you mean notation of m(t)...
- That being the "message signal".
as mentioned. Kf or easier to see here:
is the frequency deviation constant...
