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, by providing an oscillator and counter controlled depending upon the duty ratio of a pulse-width modulated wave.
CONSTITUTION: Although pulse oscillator 2 generates N-1 pulses (b) within repetitive period T of pulse-width modulated wave 1, N-scale counter 3 counts (n) pulses (c) during T1 at a certain ratio of modulated wave 1. Since the output of counter 3 is binary, converter circuit 4 converts it into a N-scale numeral and dispaly elements of display unit 5 are lighted. In this case, display elements O to (n) are lighted in sequence corresponding to the count, so that (n+1) display elements will appear to be lighted.
