Abstract
An input analogue signal is converted to a two-valued signal and then it is supplied to each encoder. Each gate signal forming circuit forms a gate signal based on an input digital signal. Each encoder encodes the above stated two-valued signal, an encoding function thereof being determined based on the above stated gate signal. As a result, each encoder outputs a result of multiplication of the two-valued signal and the digital signal in the form of a binary digital signal.
