Claims (1)
号が線順次で供給され、両色差信号を同じ周波数
−電圧変換軸上で復調する１軸復調回路と、この
１軸復調回路に接続され、容量結合遅延素子によ
り１水平走査期間遅延した復調信号とそうでない
復調信号との切り換えにより、色差信号ごとに同
時化する同時化回路とを設けてなる色復調器。 Two types of frequency-modulated color difference signals with different center frequencies are supplied line-sequentially, and a single-axis demodulation circuit demodulates both color-difference signals on the same frequency-voltage conversion axis. A color demodulator is provided with a synchronization circuit that synchronizes each color difference signal by switching between a demodulation signal delayed by one horizontal scanning period and a demodulation signal not delayed by an element.
