Question

A) Determine the first harmonic frequencies for fa=3Khz and fb= 8kHz

B) Determine the cross product frequencies produced for m and n taking values 1 and 2 only.

Answer 1

Solution of A)

Given, the fundamental frequency of fa is 3kHz and

fundamental frequency of fb is 8kHz.

Since the first harmonic frequency is equals to the fundamental frequency.

Hence, the first harmonic frequency of fa=3kHz.

and, the first harmonic frequency of fb=8kHz.

Solution of B)

The cross product frequencies produced for m and n taking values 1 and 2 is shown in table in the below image.
