Amplitude Modulation, Distortion.
Cuthbert Nyack
The applet below shows an amplitude modulated signal in red and
how it can be affected by changes in the relative
magnitude and phase of the 2 sidebands. This arises when the signal
is passed through circuits like RC and single tuned LCR circuits.
Some eg parameters showing distortion are:-
eg parameters 2.0, 0.5, -100.0, 0.3, -30.0, 0.0
eg parameters 2.0, 0.5, -20.0, 0.3, -30.0, 0.0
eg parameters 2.0, 0.5, -0.0, 0.3, -90.0, 0.0
eg parameters 2.0, 0.5, -100.0, 0.3, -30.0, 0.0
eg parameters 2.0, 0.3, -20.0, 0.5, -40.0, 0.0
eg parameters 2.0, 0.5, -100.0, 0.3, -30.0, 0.0
eg parameters 2.0, 0.3, -100.0, 0.5, -30.0, 0.0
eg parameters 2.0, 0.4, -90.0, 0.4, -0.0, 0.0
When activated, the gif image below shows how the applet should
appear.
