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