DEVICE TO COMPENSATE FOR NOISE IN WIDE-BAND SIGNAL RECEIVERS Russian patent published in 2000 - IPC

FIELD: radio engineering, specifically, communication system with wide-band signals. SUBSTANCE: device has first multiplier, rejection filter and second multiplier connected in series, subtractor, third multiplier and output filter whose output is output of device. One of inputs of subtractor is connected to output of first adjustable delay element whose input is linked to input of first multiplier and is input of device. Output of generator of reference signal is simultaneously connected to another input of first multiplier and input of adjustable delay element. Output of the latter is connected at same time to inputs of second and third multipliers. EFFECT: increased noise immunity. 2 dwg
