<p>A two digit display system includes an AC line operated transformer with a center tapped secondary supplying a pair of diodes to produce half wave rectified voltages 180.degree. out-of-phase for alternately activating two 7-segment digital display devices. One half wave voltage is reshaped and supplied to a multiplexing circuit for alternately supplying, in synchronism with the corresponding display device activation, BCD information from separate tens and units storage devices to a single decoderdriver for conversion of the BCD information into digital information for display.</p> |
