Total harrnonic distortion is only 0.01% in amplitude-stabilized oscillator delivering 7 VRMS. Opamp A1 has closed-loop gain of 3. Regenerative feedback through bandpass filter C1-C2-R1-R5 determines frequency of oscillation. Output is stabilized by multiplier whose control voltage is derived from integrator A2.-R. Burwen.
