Question

A 20 MHz carrier is modulated by a 400 Hz modulating signal. The carrier voltage is 5V and the maximum deviation is 10kHz. Write down the mathematical expression for the FM and PM waves. If the modulating frequency is increased to 2 kHz keeping everything else constant write down the expression for the FM and PM waves.
