NTSC Component Buffer Amplifiers
Figure 12
The Y signal is buffered by transistors 7800 and 7801. This is an impedance matching circuit. This
circuit does not invert the signal. The Pb signal is amplified by 7802 and buffered by 7803. The Pr
signal is amplified by 7804 and buffered by 7805. The Pb and Pr signals are inverted.
