Abstract
PURPOSE:To perform the operation efficiently with a simple constitution, by applying operation parameters to the setting circuit consisting of a DC power source and plural variable resistors analogically and by subjecting the result operated by a processor to A/D conversion and by sample-holding and outputting the A/D conversion result. CONSTITUTION:Operation parameter setting circuit 50 consisting of DC power source 51 and variable resistors 52-55 is provided to the outside of processor 20. The analogue signal is converted to a digital signal and is supplied to processor 20, and the operation is performed by CPU23, data memory part 22, ROM24, and so on. The operation result is sent to D/A converting device 30, and the analogue output of device 30 is led to analogue signal holding circuit 40 and is sample-held and is output from output terminal 45. As a result, various operation parameters are given analogically with the simple constitution, and they are prevented from being lost at a power failure time.
