Abstract
The signal x to be transmitted is converted to the redundant code f(x) by the redundancy coder and transmitted via the isolating capacitor of the isolator . When the signal f(x) redundancy-coded and transmitted is the coded word f(xi), the decoder 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 corrects the error and outputs xi which is inferred as an original signal.
