Question

A phase modulator produces a maximum phase shift of 45 degrees. The modulation frequency range is 300 to 4000 Hz. What is the maximum frequency deviation possible

Answer 1

Answer:

Maximum frequency deviation is 2616.29509 Hz

Maximum frequency deviation=(4000-3000)cos45

Max frequency deviation=2616.29509 Hz

Answer 2

The maximum frequency deviation possible is 2616.29509.

Given maximum phase shift is of 45 degrees.

The modulation frequency range is 300 Hz to 4000 Hz.

We have maximum frequency deviation = (higher frequency - lower frequency)cos$\alpha$

Here $\alpha$ is the phase shift angle.

So, maximum frequency deviation = $(4000-300)cos45$

$= 3700\times\frac{1}{\sqrt{2} }$

$=\frac{3700}{1.414}$

$=2616.29509039$.

Hence the maximum frequency deviation possible is 2616.29509.
