PURPOSE:To perform the transmission of digital signal with high accuracy, by specified signal processing if bit variation is present between the input and output. CONSTITUTION:Taking a look at the digital signal at the reception section RX, there might be slight bit variance among input digital signals due to the error in the D/A converter 70, transmission line 80, and A/D converter 90. If the error produced from this transmission system is less than n-bit, the effective bit of the digital signal fed to the transmission section TX is taken more than n+2-bit and n+1-bit or less is taken as ''0''. Further, to either one of the transmission section TX and the reception section RX at least, digital signal in which ''1'' at n-bit or less and ''0'' at n+1-bit or more are achieved is fed to the digital signal. Thus, the effect of carry and borrow on n+2-bit or more due to the variance in n-bit can be avoided. |
