Circuits Designed by Dave Johnson, P.E. :
Video Signal Edge Enhancements  -  I designed this circuit many years ago, based on the claims that the technique would improve the quality of standard TV images. The circuit adds information to the edges of the objects and was reported to bring out more detail. After building and testing. . . Circuit by Dave Johnson P.E.,  07/08/00

Edge Detector runs off of single supply  -  12/04/97 EDN Design Ideas:  You can use a single-supply circuit to generate a pulse on both the rising and the falling edges of a signal for use with counters or similar devices that require only a rising edge to trigger (Figure 1a).  R1 and C1  form a differentiator that converts rising edges to positive spikes and falling __ Circuit Design by Joe Meloche, Ingersoll-Rand Fluid Products Division, Bryan, OH

Minimum Mass Waveform Capture & Display     -  The result was a project that includes a waveform capture circuit, a graphic LCD (Liquid Crystal Display) and a control panel with LED indicators.  The details of the Graphic LCD display unit, composed of the LCD module, a serial interface, and bias supply were published earlier on this site,  __ Designed by Dick Cappels

Waveform Conversion  -  sine to square and square to sine __  Contact:  Charles Wenzel of Wenzel Associates, Inc.

Waveform Monitor with LCD      -  The result was a project that includes a waveform capture circuit, a graphic LCD (Liquid Crystal Display) and a control panel with LED indicators.  The details of the Graphic LCD display unit, composed of the LCD module, a serial interface, and bias supply were published earlier on this site,  __ Designed by Dick Cappels
