FM SIGNAL GENERATOR OR WOBBULATOR


Posted on Feb 4, 2014

With sine-wave input, RCA CA3046 transistor array connected as VCO can be used as low-distortion FM signal generator. With sawtooth input, same arrangement serves as wobbulator. Increasing size of timing capacitor reduces op-erating frequency, permitting use down to audio frequencies as voltage-controlled oscillator in electronic organ. -J. L. Lins
