Abstract

PURPOSE: To simplify constitution considerably, by using one D/A converter for a data conversion unit and by switching its input and output signals by a switching unit.
CONSTITUTION: When all switches of switching unit SW are switched to the REC (recording) side, analogue signal Ar to be recorded is applied to one end of current and voltage variable resistance Rc of D/A converter 2-1, and the output of digital value determining unit 2-3 is applied to the digital input through switch SW3, and therefore, digital output Dr is applied to digital signal processing unit 3 and is processed. Next, when all switches of unit SW are switched to the PB side, the reproducing mode is set, and the bit input signal given to converter 2-1 is digital signal Dp for reproducing from digital signal processing unit 5, and the output signal of converter 2-1 is applied to current voltage conversion unit 6-3 consisting of operational amplifier 6-2 and feedback resistance Rf, and therefore, output current I0 of converter 2-1 becomes analogue voltage output Ap. As a result, constitution is simplified.
