You guys are hilarious! What do you do for real fun?

Now answer my goddamn post so that I can get on with my task, and the bunch
of you can finish your 101.1 (humour and ridicule class) served with a
generous heaping of chest beating!

Keep up the good work

OK, it's been one heckuva long time since I took EE courses but I do
remember that a square wave has a spectrum of *every* frequency. Why
do you pick on the odd harmonics as noisemakers?


Because a symmetrical square ware contains odd harmonics only, decaying in
amplitude . The fourier series looks like F + 1/3*3F + 1/5*5F + 1/7*7F
.......

A sawtooth contains all harmonics like F + 1/2*2F + 1/3*3F + 1/4*4F......
