Abstract

PURPOSE: To obtain a simply-constituted and easy-to-see circuit which is able to select the size of its display part freely and to make linear display, the providing an oscillator and two counters controlled depending upon the pulse width of a pulse- width modulated wave.
CONSTITUTION: By being supplied with pulse-width modulated wave 1 (a), pulse oscillator 2 generates pulses (b), whose number is greater than (PxN-P) and less than (PxN-1), during repetitive period T of modulated wave (a). This pulse output is counted by P-scale counter 3 and counter 4 composed of N-scale counter 7, and its output is converted from a binary numeral into a N-scale numeral of N outputs by converter circuit 5 composed of code converter 8, so that display elements of display unit 6 will be lighted corresponding to the counting number. At this time, display elements 0 to (n) are lighted in sequence, so that (n+1) display elements will appear to be lighted.
