Abstract. The usage of digital filters with infinite impulse response (IIR) allows reducing computing and hardware costs significantly. However, the instability of such filters prevents their wide usage. This problem is obvious when creating narrowband filters under conditions of limited hardware resources and limited capacity of digital filter coefficients. This work aims to analyze the stability of a two-stage form, in particular an interpolated IIR filter and a smoothing filter with an infinite impulse response.

Keywords: digital signal processing; narrowband digital filter; IIR-filter; interpolated filter; smoothing filter; multistage filter.
