Interface circuit diagram using black and white TV as display terminal

This interface circuit is added between the standard video signal output of the computer and the TV, and can amplify the standard 1V (peak-to-peak) video signal to 3V (peak-to-peak).

T1 and T2 form a negative feedback amplification circuit with a wide frequency band range. The circuit amplification factor is mainly determined by the ratio of R1 and R8.
