# Solution: Calculate the frequency deviation and the carrier swing

#### Problem Statement: Principles of Communications

Modulation Problem Solving

Calculate the frequency deviation and the carrier swing of a frequency- modulated wave which was produced by modulating a 50.4 MHz carrier. The highest frequency reached by the FM wave is 50.415 MHz. Then calculate the lowest frequency reached by the FM wave. If the frequency of the modulating signal is 5 KHz, what is the bandwidth of the FM wave?

The frequency deviation is equal to 15 kHz and the carrier swing necessary is equal to 30 kHz. The lowest frequency reached by the FM wave is 50.385 MHz and the Bandwidth is equal to 40 kHz.
