Representation of phase modulated signal

The equation v(t) = A cos [ω_ct +k_p Φ(t)] represents the signal as

Options:

a) Phase modulated signal
b) SSBSC signal
c) DSB SC signal
d) None of the above
Where, A is a constant that represents Amplitude and ω_c represents carrier frequency and k_p is the phase sensitivity of the modulator.

Correct Answer: a) Phase modulated signal

Explanation:

A phase modulated wave is given by
v(t) = A cos [ω_ct +k_p Φ(t)]
A= amplitude
Φ(t)= baseband signal
ω_c = carrier frequency
k_p = phase sensitivity of the modulator.
