レコーダの色信号処理回路。In a color signal processing circuit of a video tape recorder, the color signal is frequency-converted to a band lower than that of the FM-modulated luminance signal and recorded, and the color signal converted to the low band is frequency-converted to the original band during playback. A first bandpass filter having a pass band through which color signals other than the color burst signal are sufficiently transmitted, a second bandpass filter having a narrower band than the first bandpass filter, and controlled by a burst gate pulse. selecting means for changing the path of the color signal frequency-converted to the light band, and mixing means for mixing the output of the first bandpass filter and the output of the second bandpass filter, A color signal processing circuit for a video tape recorder, characterized in that the signal passes through a second bandpass filter.
