The proposed high-pass filter with a fractionally rational transfer function consists of sections, connected in series, the number of which is equal to the order of the filter. Each filter section contains a differential amplifier, a multiplier, an adder, and a time delay element. The noninverting input of the differential amplifier is used as an input of the filter section. The output of the differential amplifier is connected to the first input of the multiplier. The second input of the multiplier is connected to the output of the correction signal source, and the output is connected to the first input of the adder and the input of the time delay element. The output of the adder is connected to the inverting input of the differential amplifier. The output of the time delay element is connected to the second input of the adder. The output of the differential amplifier is used as the output of the filter section. The output of the last filter section is used as the output of the filter.
