Abstract
The signal x to be transmitted is converted to the redundant code f(x) by the redundancy coder 6 and transmitted via the isolating capacitor 2 of the isolator 50. When the signal f(x) redundancy-coded and transmitted is the coded word f(xi), the decoder 7 outputs xi which is inferred as an equivalent original signal and when an error occurs and the signal f(x) does not match the coded word f(xi), the decoder 7 corrects the error and outputs xi which is inferred as an original signal.
