Summary:FIELD: radio engineering. SUBSTANCE: device has series-connected first subtractor 1, first multiplier 2, third subtractor 9, band filter 3, phase shifter 4, second multiplier 5, second subtractor 6, first uncoupler 7 whose output is connected to other input of first subtractor 1. Inputs of first and second subtractors are combined and function as input of device. Output of copy signal generator 11 is connected to respective inputs of first and second multipliers 2 and 5. Inputs of third and fourth subtractors are combined and connected to output of first subtractor 1. Output of third subtractor 8 is connected through uncoupler 10 to other input of fourth subtractor 9. Second input of third subtractor 8 is connected to common point of output of band filter 3 and input of phase shifter 4. Common point of output of first subtractor 1 and input of multiplier 2 functions as output of device. EFFECT: improved design. 2 dwgc
