ABSTRACT:
A circuit for identifying the standard of a color television signal includes a gain-controlled amplifier for standardizing an amplitude of oscillations of a composite video baseband signal during a reference burst centered on a reference level. The burst is designed for use by band-pass filters for identifying the standard and is preceded by a line synchronization pulse. The circuit also includes a device upstream of the amplifier for eliminating line synchronization pulses.
