Abstract
PURPOSE:To obtain the optional voltage with a small capacity by deciding both the upper and lower limit value of the voltage variable range through the voltage setting unit to memorize these value into the fixed memory device and then extracting the desired voltage out of the memory device by means of the output voltage selection switch and the encoder. CONSTITUTION:The voltage setting switch provided on keyboard 1 is operated to decide the upper and lower limit value of the voltage variable range plus the type of the linear or logarithmic variable curve. These decided factors are memorized in ROM3 functioning as a fixed memory unit via line 11 and CPU2 which is controlled by data bus line 10 and clock oscillator 5. Then switch SW for selection of the output voltage is operated to actuate encoder 6, and then the voltage memorized in ROM3 is read out via gate 7 to be delivered via gate 7 again after converted into the desired voltage by means of D/A converter 9 and via writing means RAM4. The area between RAM4 and converter 9 is connected to bus 10 via gate 8.
