Abstract

PURPOSE:To obtain a pulse width signal proportional to input data, by sending digital data of the output register of the integration type A/D converter to the preset counter and by counting this data until the clock pulse is counted up. CONSTITUTION:Analogue input 10 is converted to a digital data by the double integration type A/D converter and is latched by output register 40 and is sent to preset counter 50. Preset counter 50 counts clock pulses 2; and when the count value becomes maximum, counter 50 resets flip-flop 70 to stop output pulse 5. The time from preset to count-up is proportional to data of output register 40, namely, analogue input 10.
