FIELD: radio engineering and communications.
SUBSTANCE: invention can be used to extract the given spectra of signals, for example, during their analog-to-digital conversions. The discrete-analog low-pass filter on switched capacitors additionally contains an additional input (14) of the device, the first (15) and second (16) series-connected additional resistors and a matching non-inverting voltage follower (17).
EFFECT: creation of a low-pass filter on switched capacitors, which provides the ability to adjust the frequency of the pole without changing the capacitances of the switched capacitors
