Q 2. For a modulating signal m(t) = 2 cos 100t + 18 cos 2000t, (a) Write expressions for Phase modulated signal,øpM (t) and Frequency modulated signal, Pem(t) when A=10, wc = 106,k, = 1000n, k, = 1. For determining opm(t), use the indefinite integral of m(t), that is, take the value of the integral at t = -00 to be 0. (b) Estimate bandwidths of øPm(t) and wfm(t).

Q 2. For a modulating signal m(t) = 2 cos 100t + 18 cos 2000nt,
(a) Write expressions for Phase modulated signal,PM (t) and Frequency modulated signal,
PEm(t) when A=10, wc = 106,k, = 1000n, k, = 1.
For determining o Pm (t), use the indefinite integral of m(t), that is, take the value of the
integral at t = -o
-00 to be 0.
(b) Estimate bandwidths of oPM (t) and oem(t).
