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,
Saw Tooth the content of nth harmonic
Waveform
is 1/1. F23 45 6 7 8
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 ath harmonic is 1/1;
except that there are no even
numbered harmonics.
Square
With pulse wave, the har-
monic content god hed PULSE WIDTH
depending on the pulse
width. It is characterized by at Soe (13)
a lack of the mth harmonic
series when the pulse width
is 1/n. The example on the
Pulse left lacks 3rd, 6th, and 9th
harmonics because the pulse
width is 1/3 (33%).
