Abstract
An apparatus for decoding data wherein only binary ZEROs are received as electronic pulses, each pulse alternating in opposite directions and wherein binary ONEs require no pulse. The apparatus includes logic for receiving the negative and positive binary ZERO pulses, retiming the pulses and generating a positive pulse for each binary ZERO pulse. The positive pulse is retimed to a pair of complementary pulses and applied to a receiving device, typically a universal synchronous/asynchronous receiver transmitter (USART).
