Saw Tooth
The
sawtooth wave contains
a fundamental
sine wave and
its Integra!
harmonic sine
waves
at a fixed ratio. The
levei of each harmonic
is as
shown on the right. When
fundamental
content is
1,
the
content of nth harmonic
is Vn.

Square
The square wave
contains
a
fundamental
sine
wave
and
its odd numbered
harmonics
at a
fixed ratio. The levei of
each harmonic is the same as
sawtooth
wave: the content
of nth harmonic
is
Vn;
except that there are no even
numbered harmonics.

Puise
With pulse wave,
the
har-
monic content greatly varies
depending on the pulse width.
It is characterized by a lack
of the nth harmonic series
when the puise width is Vn.
The example on the left lacks
3rd, 6th, and 9th harmonics
because the puise width is
V3 (33%).
