Abstract

PURPOSE: To enable to extend the constitution of the bar graph display unit and to offer it with low cost, by making suitable for the capacity of bar graph through the cascade connection of the unit circuit, by selecting the output pulse train of each stage to the binary counter at the A/D conversion section.
CONSTITUTION: The unit consists of the binary counter 8 is cascade connection of the unit counters, which outputs the input clock pulse divided pulses 10a, 10b, 10c, and carry out pulse 11, D/A converter 7 which converts the data in the counter 8 into analog value in the sampling period of the external input analog signal 4 by the period of the pulse 11, comparator 6 comparing this output with the signal 4, A/D converter 12 which passes through the number of pulses proportional to the analog signal 4 by the output of the comparator 6, shift register 14 sequentially storing the number of pulses in shift, and the memory section consisting of the latch circuit 15 storing the output of the shift register 14. Thus, the constitution of the bar graph display unit can be extended.
