Abstract
An improved video synchronizing signal separator for separating luminance and synchronizing signal components, respectively, from a composite video signal. Separate luminance and synchronizing channels are supplied with the composite video signal, each channel including a biased diode and an output attenuator. The diodes are poled in opposite directions to conduct when the particular threshold level established by the bias voltage applied thereto is exceeded. As an example, the diode in the luminance channel may be positively poled to conduct when the luminance signal component exceeds a positive threshold level and the diode in the synchronizing channel may be negatively poled to conduct when the synchronizing signal component exceeds a negative threshold level. The positive-going luminance signal component serves to cut off the diode in the synchronizing channel and the negative-going synchronizing signal component serves to cut off the diode in the luminance channel.
