1KHz Square Wave Generator Circuit

Posted on Feb 6, 2014

Here`s a design for a simple 1KHz square wave generator using a few components and the LM3909 that is useful for testing audio equipment. The circuit is based from the IC. It is powered from a single 1. 5V battery cell and the maximum amplitude of the output signal is 1. 1V. With P1 you can adjust the symmetry of the square wave signal and with P2 th
