Abstract: An event counter has dual counting channels, each employing a ripple counter, and a timing generator supplying square wave switching signals of opposite phases to gates at the inputs of the two counters, the switching signals having a much greater periodicity than that of events to be counted, so that one, and only one, of the counters is counting at any one time. The timing generator also generates control signals to transfer a count from whichever counter is inactive to an associated latch and then reset the counter. When a counter is again enabled, the switching signal is also used to enable output from the latch of the previously stored count. This arrangement enables ripple counters to be used in an arrangement providing both continuous counting and continuous output availability.
