FIELD: radio engineering.
SUBSTANCE: invention relates to radio engineering. To achieve the effect, an active RC high-pass filter of the Sallen-Key subclass is proposed, which contains an input (1) and an output (2) of the device, the first (3) and second (4) frequency-setting capacitors, the first (5) and second (6) frequency-setting resistors , output voltage follower (7), first (8) and second (9) additional resistors, third (10) and fourth (11) additional resistors, first (12) additional voltage follower, second (13) additional voltage follower, third ( 14) additional voltage follower.
EFFECT: creation of a high-pass filter of the Sallen-Key subclass, which provides for the possibility of independent adjustment by different resistors of the pole frequency, the quality factor of the pole and the transmission coefficient.
