[Nicholas Murray]’s Composite Test Pattern Generator is a beautifully-made, palm-sized tool that uses an ESP32-based development board to output different test patterns in PAL/NTSC. If one is checking ...

There have been several designs of test pattern generators published in the past, invariably they produce the standard cross-hatch pattern, possibly horizontal and vertical lines, and may-be a ...

CRTs don’t last forever, and neither do the electronics that drive them. When you have a screen starting to go wonky, then you need a way to troubleshoot which is at fault. A great tool for that is a ...

Engineers are beginning to appreciate that, from prototypes early in the design cycle through to final system test, a digital pattern generator (DPG) speeds up system debug and therefore shortens the ...

The trend toward device miniaturization has made digital circuit testing both essential and increasingly complex. To achieve complete fault coverage, a large number of test patterns are applied, which ...
