چکیده
This paper presents simple method for the narrowband low-pass FIR (Finite Impulse Response) filter design. The method is based on the IFIR (Interpolated FIR) structure where the model filter is the ST (Stepped Triangular) impulse response filter cascaded with the simple compensator.

An Efficient Method for Narrowband FIR Filter Design
A new efficient method for implementing narrowband FlR jilters is presented. The method is based on an lnterpolated jilter (lFlR) structure and a cascade of comb and integrator (ClC) structures. The novelty ofthís technique ís that the ClC structure is used as an image suppressor in an lFlR structure. The method is useful for narrowband FlRjilter design and some design examples for lowpass and ...
متن کاملOne Method for Design of Narrowband Lowpass Filters
This chapter describes a design of a narrowband lowpass finite impulse response (FIR) filter using a small number of multipliers per output sample (MPS). The method is based on the use of a frequency-improved recursive running sum (RRS), called the sharpening RRS filter, and the interpolated finite impulse response (IFIR) structure. The filter sharpening technique uses multiple copies of the sa...
متن کاملNarrow-band and wide-band single filter frequency masking FIR filters
In this paper single filter frequency masking FIR filters are discussed. We briefly review the previously proposed lowpass narrowband filters and propose a design method for highpass narrow-band filters. Wide-band filters are also discussed. The proposed approach uses several identical filters, except for periodicity, which are mapped to a single hardware structure using folding. This results i...

This paper presents a lowpass narrowband filter design method with a small number of products per output sample (MPS). The method is based on the use of a sharpened Cascade Integrator-Comb (CIC) filter and an Interpolated Finite Impulse Response (IFIR) structure. INTRODUCTION In many communications and signal processing systems it is necessary to isolate a very narrow band signal from a very wi...
متن کاملComb-based Method for Narrowband Fir Filter Design
FIR (Finite impulse response) digital filters are known to have some very desirable properties such as linear phase, stability, and absence of limit cycle. However their applications generally require more computation. In this paper we consider the simple method to design a multiplier-less narrowband FIR filter. The method is based on well known IFIR (Interpolated FIR) structure. The novelty of...
