Abstract
A junction transistor circuit capable of performing the color synchronization function of a color television receiving system is described. The circuit employs a single-junction transistor which serves as an oscillator-amplifier, phase detector, and current-controlled variable reactance in the generation of an accurately phased color reference carrier. A series mode quartz crystal filter in the feedback loop of the oscillator enables the circuit to perform well in the presence of noise interference up to a 1:1 signal-to-noise ratio.
