МСЕ (Voltage Controlled Filter)
Theoutput signal of DCO goes to the Mixer, then to the
VCF to be filtered. Each VCF lets lower frequency har-
monics pass and cuts off the higher ones. In other
words, it is a usual low pass filter. By controlling the
cutoff point and resonance, the waveform changes,
thereby the tone color alters.
