Abstract : A digital display system is provided for visually indicating the amplitude of a received signal. A plurality of reference signals incrementally graduated from a low amplitude to a high amplitude is applied as first inputs to a polarity of comparators and the received signal as applied as the second input. The comparators produce an output of polarity commensurate with the instantaneous difference between its inputs and a plurality of series-connected light emitting means, each connected between the outputs of two adjacent comparators, is responsive to a predetermined electrical potential for generating light energy so that the instantaneous amplitude level of the received signal is visually indicated by the actuation of a single such light emitting means at a time.
