Abstract
Disclosed are an apparatus and a method for transmitting an analog signal, and an analog signal multiplexer. The apparatus comprises a photocoupler to receive an input analog signal and transform the input analog signal into an output analog signal, which varies with the input analog signal in a manner of non-linearity. The apparatus further comprises a non-linearity correcting unit to receive the output analog signal and correct the non-linearity to output a corrected output analog signal. An analog signal may be transmitted with a photocoupler.
