PHASE_SHIFT_SINE_WAVE

Uses NE571 analog compandor as phase-shift oscillator, with internal inverting amplifier serving to sustain oscillation. C1, C2, and C3 are timing capacitors, while R1 and R2 serve for phase-shift network.Suitable for use only as spot-frequency AF oscillator, with frequency being varied by changing values of C1, C2, and C3. Total harmonic distortion is only 0.01% at 3-V output.-W.G.Jung, Gain Control IC for Audio Signal Processing, Ham Radio, July 1977, p 47-53.
