Abstract
An adder 22, a quantizer 20, and a variable integrator 24 execute A/D conversion and the result is stored in a memory 12. A time constant of the variable integrator at this time is controlled by a time constant controller 25. On the other hand, data from the memory is integrated by a variable integrator 28 to provide an analog signal. At this time, control data of the time constant controller 25 is transferred via a memory 32 to a time constant controller 33, which then uses the transferred control data to control the time constant of the variable integrator 28. When a mode is changed, switches 34 and 35 are turned off. Therefore, a signal with no input can be written into the memory 12 for initializing the memory 12.
