Quasi-digital NTSC color bar generator

An NTSC color bar generator is described that consists of a simple, low-cost quasidigital circuit. The generator includes a master oscillator, signal divider circuitry, a luminance generator, a delay circuit, and a burst generator. The measured performance shows a differential gain of 3%, a differential phase of 4 degrees , and a linearity of less than 2.8%.<
