# Solution: Calculate the carrier and modulating frequencies, the modulation index and deviation

#### Problem Statement: Principles of Communications

Modulation Problem Solving

The equation of an angle-modulated voltage is v = 10 sin (108t + 3 sin 104). What form of angle modulation is this? Calculate the carrier and modulating frequencies, the modulation index and deviation, and the power dissipated in a 100-ohm resistor.

The given is Frequency Modulation; the carrier frequency is equal to 17.189 Hz; the modulating frequency is equal to 16.55 Hz; the modulation index is equal to 3 and deviation is 49.65 Hz; The power dissipated in a 100-ohm resistor is equal to 0.5 W.
