Hi
Would like any guidance about removing harmonic distortion from a sine wave created from a phase shift oscillator, I have come across the following two circuits but not sure if I can use them to remove any unwanted harmonics I would like a fourier transform with a peak only at 1kHz and other frequencies to be attenuated.
Thanks Art
I have attached documents with two kinds of circuits, one called
Total Harmonic Distortion (THD) Test Circuit
and the other:
Precision Absolute Value Circuits
