Abstract
In square wave signal processing, a plural signal combiner is provided with a reference input along with differential inputs for other signals to be combined. Each differential input terminal is provided with an emitter load by means of a plural emitter transistor connected to have a constant collector current. The combiner can process square wave signals to extract phase information.
