Filter-based 50 Hz Sinewave Generator

-

Published in issue 345, July 2005

Filter-based 50 Hz Sinewave Generator
The circuit shown here combines the functions of a low-pass filter and an integrator, presenting a novel approach to creating a precision 50-Hz source with relatively low distortion.
The circuit is free from any kind of gain setting network.
