Using a 74HC132E to square up the wave

A nice gentleman from sci.electronics.* newgroup suggested I use a 74HC132 on his web page here.[local copy]

Below is the result of using this design, it worked perfectly. Only required one IC, one resistor, and one capacitor. Very simple.

Input is on the top, and output is on the bottom. A nice square wave. Now ignore some of the sloppy noise on the signal — this will get cleaned up with a pull-up and a small cap. This will be a heck of a lot easier to sample.

More updates to come!
