چکیده

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 highpass jilters are given.

Simple Method for Lowpass Narrowband Fir Filter Design

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.

One Method For Design of Lowpass Narrowband Filters

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...

Formulating Wideband Array-Pattern Optimizations

Custom design of wideband digital array patterns requires a systematic approach to mapping design specifications to a program understandable by optimization engines. We show that, like in the narrowband case, wideband array patterns are closely related to multidimensional FIR filter responses, suggesting the adaptation of powerful and efficient filter design techniques to the array problem. Pre...

One 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...

Narrow-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...
