Field of the Invention The present invention relates to an apparatus for transmitting and receiving digital data. The present invention relates to a multiplexer 13 for encoding and outputting a plurality of digital signals represented by two logic levels to be transmitted into one digital signal represented by a plurality of logic levels. 23); And multiplexers 14 and 24 for decoding and outputting one digital signal represented by the plurality of logic levels and the plurality of digital signals represented by the two logic levels.

이와 같이 본 발명은 전송하고자 하는 디지탈 신호의 논리 레벨을 다양하게 부호화하여 전송하고, 논리 레벨이 다양하게 부호화되어 전송된 신호를 원래 디지탈 데이타로 복호할 수 있게 하므로써 하나의 전송 라인을 통하여 복수개의 데이타를 동시에 전송할 수 있어 데이타 전송 시간을 단축할 수 있다는 효과가 있다.As described above, the present invention allows a plurality of pieces of data through one transmission line by encoding and transmitting a logic level of a digital signal to be transmitted in a variety of ways, and decoding a transmitted signal having variously encoded logic levels into original digital data. Simultaneously transmit the data can reduce the data transfer time.
