Abstract
A signal transmission device adapted to transmit an n-bit parallel digital signal is used for avoiding a transmission error. The device includes a detector for receiving a first and a second n-bit digital data consecutively occurred in the n-bit parallel digital signal, proceeding a first calculation to obtain a changed value, and outputting an indicating signal while the changed value is larger than a threshold, an encoder electrically connected to the detector for receiving the indicating signal and the second n-bit digital data, proceeding a second calculation, and outputting an encoded second n-bit digital data to reduce the changed value between the first n-bit digital data and the encoded second n-bit digital data below the threshold, and a decoder electrically connected to the detector and the encoder receiving the indicating signal and the encoded second n-bit digital data, proceeding a third calculation, and recovering the second n-bit digital data.
