    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...
