21 An FM signal has a deviation of 10kHz and a modulating frequency of 2kHz. Calculate the modulation index.
What are the maximum and minimum values for the instantaneous frequency of the modulated signal?
33 An FM signal has a deviation of 10 kHz and is modulated by a sine wave with a frequency of 5 khz. The carrier frequency is 150 MHz, and the signal has a total power of 12.5 W, operating into an impedance of 50 ohms. What is the modulation index?
