Improvements in Systems of audio signal processing Circuits of color difference in Zion in color TV receivers

摘要

Circuit to conduct Training in matrices of the outputs of the color difference Signal DEModulator Colour alternatingly. Presents a couple of push-pull Colour DEModulator (10) and (20), whose mission genwerar signals of different color (+ I and + q) from the Recovery of the signal of color difference of colour subcarrier Modulated.Three differential Amplifier Circuits (70, 80, 90) delivered their signals to three Networks of level Displacement (100, 110, 120).
