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 Design by Joe Meloche, Ingersoll-Rand Fluid Products Division, Bryan, OH Improve the quality of standard TV images - I designed this circuit many years ago, based on the claims that the technique would improve the quality of standard TV images.

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.
