Description : CGA/EGA uses a digital signal, referred to as TTL (Transistor-Transistor Logic), for the transmission of its video signal. TTL is a signal that operates in an on or off state only, thus limiting the amount of displayable colors. Intensity bits are used to expand available colors up to four times the original amount. Commonly used in low resolution computers.
