DECODER FOR DECODING THE CHROMINANCE SIGNAL OF A COLOR TELEVISION SIGNAL

摘要

A decoder circuit for PAL and SECAM television signals which has two reflection type delay lines. A horizontal frequency switch alternately applies the chrominance signal to the delay lines. The switch may be a pair of diodes or transistors. Since each delay line is of the relecting type, it need only contain half of the delay line material normally required.
