Harmonics of a Square Wave

Harmonics of a Square Wave....

1. Homework Statement

A 200kHz square wave with a fundamental frequency amplitude of 15V. Find amplitude of the third harmonic.

2. Homework Equations

This is what I do not know. I know this is a fourier transform problem but just don't know what to do with it.


3. The Attempt at a Solution

I just took 15V and substracted (1/3) from it to get 14.6667 Volts.

You need to do the transform, or at least look it up. The amplitude coefficients are expressed as a function of harmonic. Post the FT and we can help if still confused.
