DEVICE FOR SIMULATION OF EQUALITY FUNCTION Russian patent published in 1996 - IPC

FIELD: computer engineering. SUBSTANCE: device has differential amplifier with large gain, absolute value generator, which input is connected to output of differential amplifier, first and second amplitude selectors which implement functions X₁ and X₂ respectively, first and second inputs of first and second amplitude selectors are connected to sign-inverting input of differential amplifier; their second ins are connected to output of absolute value generator; outputs of first and second amplitude selectors are joined and serves device output. EFFECT: detection of equality of two analog signals X₁=X₂=X and and output of signal . 3 dwg
