FIELD: radio engineering.
SUBSTANCE: disclosed is a second-order discrete-analogue filter on switched capacitors with two electronic switches, in which first (7) and second (8) series-connected electronic switches are connected between the output of voltage follower (12) and inverting (4) input of differential operational amplifier (3), and the common unit of first (7) and second (8) series-connected electronic switches is connected to the common power supply bus through series-connected frequency-setting resistor (13) and second (9) frequency-setting capacitor.
EFFECT: reducing the number of resistors of the frequency-setting circuit and providing the possibility of single-element frequency adjustment.
