EQUALITY FUNCTION REPRODUCING DEVICE Russian patent published in 1997 - IPC

FIELD: automatic control and analog computer engineering; recording equality of two analog signals, discriminating time-amplitude coordinates crossing two analog unipolar processes, etc. SUBSTANCE: device has series-connected differential amplifier and module shaper; newly introduced in device are first amplitude selector reproducing function of infinitely valued logic and second amplitude selector reproducing function ; first inputs of first and second amplitude selectors are connected to inverting input of device and their second inputs, to output of module shaper; outputs of first and second amplitude selectors are combined and form device output. EFFECT: enlarged functional capabilities. 3 dwg
