Abstract:
An electric circuit with a plurality of inputs, each input receiving a train of pulses. Each pulse of each train sets a latch of cross-coupled logic gates to an output of logic 1. A clock generating regular voltage pulses is connected in parallel to the latches so as to reset the output of each gate to logic 0 in series with each other. The plurality of outputs from the latches is passed through a common gate to form the output train of pulses as an addition of the plural inputs.
