Abstract
PURPOSE: To make it possible to regenerate an excellent video signal by a simple circuit constitution by converting a chrominance signal on the SECAM SYSTEM into low-frequency one by a frequency-demultiplying circuit and by converting the regenerated signal into the original chrominance signal again by a frequencymultiplying circuit.
