**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.
