ABSTRACT:
Apparatus for converting analog to digital signals and vice versa is described wherein a storage capacitor provided at an input of a codec operating in accordance with the iterative method and designed for receiving analog signals to be converted into digital signals is further connected either to a constant current generator or to the digital-to-analog converter of the codec for a period during which a voltage may be applied to the capacitor which correponds to a digital signal that is to be converted into an analog signal and that has been applied to the digital-to-analog converter. A two-wire circuit transmitting analog signals in both directions of transmission is connected to the storage capacitor. The resonance-exchange-of-charge method is used for the transmission of the analog signals.
