Figure 11.27
Frequency spectrum for a sine wave with mild distortion
present (third and seventh harmonic components are visible)
Figure 11.28
Frequency spectrum for a sine wave with severe distortion
present (third, fifth, and seventh harmonic components can be clearly seen)
Figure 11.27 shows the same waveform as that shown in Figure 11.26 but
with mild distortion present. The waveform is no longer a pure sinusoid and
the third and seventh harmonic components have become visible.
Figure 11.28 shows the frequency spectrum of a severely distorted sine wave
in which third, fifth, and seventh harmonics are present (the ninth harmonic is
also present but cannot be seen due to the sweep setting).
