Answer to Question #262292 in Other for allyza

Question

1) A 162-MHz carrier is deviated by 12 KHz by a 2-KHz modulating signal. What is the modulation index?

2) The maximum deviation of an FM carrier with a 2.5 KHz signal is 4 KHz. What is the deviation ratio?

3) For problem 1 & 2, compute the bandwidth occupied by the signal, by using the conventional method and Carlson’s rule. Sketch the spectrum of each signal, showing all significant sidebands and their exact amplitudes.

4)For a single-frequency sinewave modulating signal of 3 KHz with a carrier frequency of 36 MHz, what is the spacing between sidebands?
