Abstract:
A signal transmission device for transmitting an n-bit parallel digital signal and avoiding a transmission error, comprising:a detector for receiving a first n-bit digital data and a second n-bit digital data consecutively occurred in said n-bit parallel digital signal, proceeding a first calculation to obtain a changed value representative of a bit number having level change in an n-bit, and outputting an indicating signal while said changed value is larger than a threshold; an encoder electrically connected to said detector for receiving said indicating signal and said second n-bit digital data, proceeding a second calculation, and outputting an encoded second n-bit digital data to reduce said changed value between said first n-bit digital data and said encoded second n-bit digital data below said threshold; and a decoder electrically connected to said detector and said encoder for receiving said indicating signal and said encoded second n-bit digital data, proceeding a third calculation, and recovering said second n-bit digital data.
