7400 competition entry: TV pattern generator

Posted on Wednesday, October 19th, 2011 in 7400 contest by DP

Ajoy built a TV pattern generator for the Open 7400 Logic competition. Using 74C14 Shmitt inverters to generate various timing signals, he later combines them using a few NAND 74C00 gates to get a B&W TV video signal generator by CCIR-B standards. A full write up explaining the operation of his circuit, along with the schematic is available.
