Abstract
An electronic comparator for selecting and outputting the larger of first and second electrical, binary-coded input values presented bit-serially, most-significant-bit first, has first and second input terminals; a logical exclusive-OR gate; a first resettable flip-flop; a second flip-flop; and a device for selecting one of the input values as an output of the comparator. In a second embodiment, the electronic comparator has first and second input terminals; a logical exclusive-OR gate; a first flip-flop synchronized with a train of bitclock pulses; a second resettable flip-flop; a third flip-flop; and a device for selecting one of the input values as an output of the comparator. Devices for generating traceback signals indicating which input values were selected and a signal indicating that the maximum value has been identified are also disclosed.
