Repeat the preceding problem assuming that the transmitter outputs are defined by

(a) x_c (t) = cos[2π(1000)t²]

(b) x_c (t) = cos[2π(900)t + 10√t]

Data From Problem 9

A transmitter uses a carrier frequency of 1000 Hz so that the unmodulated carrier is A_c cos(2πf_ct). Determine both the phase and frequency deviation for each of the following transmitter outputs:
(a) x_c (t) = cos[2π(1000)t + 40 sin (5t²)]

(b) x_c (t) = cos[2π(600)t]
