Abstract

An original method of one bit digitization of two level analog video has been proposed and implemented. A corrected analog video waveform is fed into three comparators with incremented reference voltages. The resulting parallel digital outputs are processed by a sequential machine into a binary video bit stream. The approach is unique in that sequential machine theory is employed to find a logic realization for a low resolution (one channel) analog-to-digital converter.
