ABSTRACT:
A video signal from a low impendance output of an amplifier device is conveyed to an image display device via a coupling path including first and second series connected resistors and a high frequency bypass capacitor coupled across the first resistor. The coupling path limits the signal drive to the display device particularly in the presence of a large magnitude video drive signal, and also compensates for high frequency attenuation of the video drive signal by an input capacitance of the display device.
