Abstract
PURPOSE: To shorten the time of a measurement by making it possible to find minimum operation pulse automatically from the number of pulses by employing a pulse width modulating circuit that provides pulse-width modulation in proportion to the number of pulses.
CONSTITUTION: Pulses generated by pulse generating circuit 10 are inputted to pulse-width modulating circuit 30 via gate 20. The output of pulse-width modulating circuit 30 is inputted to memory control terminal 18 of memory circuit 1. The minimum write pulse width of memory circuit 1 can be found automatically by counting the number of pulses inputted to pulse-width modulating circuit 30 until memory circuit 1 is turned on.
