Digital display circuit displayable in analog fashion

摘要

A display circuit for displaying analog input voltages in a digital fashion using a parallel comparison type analog-digital converter includes a voltage generator for generating a plurality of reference voltages quantized at a predetermined voltage width, a plurality of comparators corresponding to the plurality of reference voltages for comparing the reference voltages and an analog input voltage as input, and display means for encoding and displaying the output of the plurality of comparators, is provided with modulating apparatus for modulating one of the inputs of each of the plurality of comparators periodically within the range of the predetermined voltage width.
