Harmonic Oscillator

Generates a fundamental and its first nine harmonics (harmonic numbers 1 - 10). Fundamental frequency is continuously variable from 5 cps to 5 kc and may be controlled internally or with an externally applied voltage. There is provision for wideband frequency modulation. The 148 is frequently used in conjunction with mixers (106, 107), gates (110), and attack generators (180) to enable precise programmed envelope control of individual overtones.
