ABSTRACT:
In a color television receiver luminance channel, transistor amplifier stage develops respective versions of input video signals across load resistors in collector and emitter circuits. Capacitor links collector to stage's output terminal, and parallel combination of inductor and resistor links emitter to output terminal. Parameter values are chosen to cause stage to provide delay-versus-frequency characteristic compensatory for delay distortion introduced by receiver's IF amplifier. Use of variable resistor as collector load resistor provides facility for adjustable peaking of luminance channel's amplitude-versus-frequency characteristic while maintaining delay distortion compensation effect.
