Abstract
The signal transmission device converts a K-bit original signal into an N-bit (N is greater than K) transmission signal in which the number of a logic high bit is identical to the number of a logic low bit, according to a lookup table in which a plurality of K-bit original signals are associated with a plurality of N-bit transmission signals by 1:1 correspondence, and transmit the N-bit transmission signal via N signal lines such that each line carries one bit, thereby minimizing the noise affecting the K-bit original signal.
Claims4
A signal transmission device, comprising:
