Sine wave-to-square wave converter Circuit Diagram

This is a simple Sine wave-to-square wave converter Circuit Diagram. Many signals are digitally generated or transmitted as square waves. It is often desirable to convert these signals into sine. In this Sine wave-to-square wave converter Circuit Diagram The sine input is ac coupled by capacitor C; Rl and R2 bias the input midway between Vn and Vp, the input threshold voltages to provide a square wave at the output.
