Abstract
A converter for converting VGA color signals to gray scale monochrome signals wherein each of the color signals, red, green, and blue, are processed through a circuit consisting of an emitter-follower, a selected value resistor, and a diode and wherein the outputs of the three circuits are connected together and across a load impedance for an analog monochrome monitor.
