Abstract

PURPOSE: To make it possible to color signals of two kind of signal sources together without lowering the purity of superposed color signals by shorting color signals via respective analog switches and then by turning ON-OFF analog switches by a signal from one signal source.
CONSTITUTION: Color signals of red, green and blue such as TV broadcast waves are applied to input terminals 13∼15 and color signals of characters and patterns are also applied to input terminals 25∼27. Both color signals are shorted, color by color, via 1st analog switch group 16 and 2nd analog switch group 28, and those shorted color signals are inputted to amplifiers 21∼23 to display two kind of signals superposed on the display screen of CRT24 at the same time. As for any input to input terminals 25∼27 for color signals to be superposed, 1st analog switch group 16 is turned OFF, so that signals can be displayed on the screen of CRT24 without lowering the purity of superposed signals.
