Figure 3-5. Sine Synthesizer and Function Selector
(A)
Waveform from integrator output to B-. Triangular
regardless of function selector position.

(B) Waveform from@to B- with selector switch in sine
position. Note distortion especially a t peaks.
(C) Waveform from@to B- with selector switch in sine
position.
This
is
the distortion component present
in waveform (B) above.
(D)
Waveform f r o m a t o @ (i. e. : difference between
waveforms (B) and (C) above. ) This is the approxi-
mated sinewave.
