ABSTRACT:
A square wave to sine wave converter of the type which utilizes an integrr, an amplifier and a sine wave shaper in the signal processing operation has an automatic gain control circuit which responds to signal variations both at the output of the integrator and the output of the amplifier to insure a constant amplitude triangular wave at the input of the sine wave shaper as the frequency of the square wave changes.
