FIELD: radio engineering.
SUBSTANCE: invention relates to radio engineering. For this, an RLC low-pass filter on voltage followers is proposed, which contains an input (1) and an output (2) of the device, a terminating resistor (3), a frequency-setting inductance (4), and a frequency-setting capacitor (5). The first (6), second (7) and third (8) additional voltage followers, the first (9) additional resistor, the second (10) and third (11) additional resistors, the fourth (12) additional resistor are introduced into the circuit.
EFFECT: creation of conditions under which an RLC low-pass filter is implemented on voltage followers with the possibility of independent tuning of the main parameters at constant values of the frequency-setting inductance or capacitance of the frequency-setting capacitor.
