ABSTRACT:
Two transistors are operated individually as emitter follower buffer amplifiers for R-Y and B-Y input signals and are operated together as an inverting summing matrix for deriving a G-Y output signal from the R-Y and B-Y input signals. All three output signals are "buffered" (i.e., provided by low impedance sources) and are subject to substantially equal delays. Advantageously, the circuit implementation requires only two transistors and three resistors to provide output signals which are (1) buffered, (2) matrixed and (3) delay compensated and which features improved reliability (due to reduced "parts count") and an economic implementation of the buffering, delay compensation and matrixing functions.
