Abstract
A code division multiplex communications system comprising: receiving circuit for receiving a radio wave and transforming the radio wave to an electric signal; delaying circuit for sequentially reading the electric signal at a timing of a clock pulse; switching circuit for shutting off a drive current of the delaying circuit at an OFF timing of the clock pulse; adding and subtracting circuit for adding and subtracting outputs of the delaying circuit in accordance with a spread code; and reproducing circuit for reproducing a transmission signal on the basis of an output of the adding and subtracting circuit. RCS95-120 is similar with respect to a point that an analog LSI matched filter is constructed by a slide capacitor system.
