Inexpensive Chrominance Circuits

The rapidly expanding color-TV receiver market has been accompanied by much new interest in reducing receiver cost. In this report novel chrominance-signal processing circuits are described which reduce the tube count with a consequent lowering of cost, and at the same time provide desirable features such as high-performance automatic chrominance control, a color indicator, and two-mode color sync-features normally omitted in low-cost designs. Included in this report are detailed descriptions of the circuits, their modes of operation, performance data, and design data.
