Representation of phase modulated signal
The equation v(t) = A cos [ωct +kp Φ(t)] represents the signal as
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 ωc represents carrier frequency and kp is the phase sensitivity of the modulator.
Correct Answer: a) Phase modulated signal
A phase modulated wave is given by
v(t) = A cos [ωct +kp Φ(t)]
Φ(t)= baseband signal
ωc = carrier frequency
kp = phase sensitivity of the modulator.
