Description
The
sawtooth
wave
contains
a
fundamental
sine
wave
and
its
integral
harmonic
sine
waves at a
fixed
ratio.
The
level
of
each
harmonic
is as
shown
on
the right.
When
fundamental
content is
1,
the
content
of
«th harmonic
is
1/n.
The
square
wave contains a
fundamental
sine
wave and
its
odd
numbered
harmonics
at
a
fixed
ratio. The
level of
each
harmonic is
the same
as
sawtooth
wave; the
content
of
nth
harmonic is
1/«;
except
that
there are
no even
numbered
harmonics.
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
pulse
width
is
1/«.
The
example on
the
left
lacks
3rd,
6th, and
9th
harmonics
because
the pulse
width
is 1/3
(33%).
