摘要: A signal level display apparatus arranged so that an ac is superposed upon either input or a reference voltage of comparator to the with differences in degrees brightness illumination light-emitting elements constituting unit when viewed externally, thereby distinguish which closer from departing away therefrom. This also displays simultaneously on said two different signals distinguished elements.
