Page 12: Description Of Block Diagram
DESCRIPTION OF BLOCK DIAGRAM 1. Line Filter & Associated Circuit. 6. Horizontal and Vertical Oscillation. This is used for suppressing noise of power input line This circuit generates the horizontal pulse and the vertical flowing into the monitor and/or some noise generated in pulse by taking the H and V sync signal. - Page 13 15. Video Pre-Amp Circuit. 16. Video Output Amp Circuit. This circuit amplifies the analog video signal from 0-0.7V This circuit amplifies the video signal which comes from to 0-4V. It is operated by taking the clamp, R, G, B drive the video pre-amp circuit and amplified it to applied the and contrast signal from the Micom(IC401).
