The harmonics are of lesser amplitude than the fundamental frequency.

That's not my memory, but it's been 25 years since I did that
homework, so I could easily be wrong.


Take a look at the url. It shows that a square wave is composed of
the fundamental and the odd harmonics. The amplitude of each harmonic
is 1/n where n is the harmonic number. That is the 3rd harmonic is
1/3 of the fundamental, the 5th harmonic is 1/5 of the fundamental,
ect.
