Step 2.2 Now change kp to pi/2 (keep all other variables the same).

Step 2.2 Plot the following equations:

m(t) = 5cos(2*1000Hz*t)

c(t) = 5cos(2*10kHz*t)

Kp = pi/2

Question 5. What is your observation?

a. The PM modulated signal remains unchanged since kp does not influence the PM index.

b. kp changes and therefore the PM Index also changes. This will impact the quality of the phase modulated signal.

c. kp only effects FM modulated signals, therefore our PM modulated signal remains unchanged.

d. All statements are incorrect.

AM modulation Message amplitude amplitude 1 2 3 time 10-2 combined message and PM signal - 1 2 3 time 109 combined message and FM si amplitude amplitude 0 1 2 3 time 10-3 time x10
