Microwave Lowpass Filters with a Constricted Equi-Ripple Passband
Lowpass filtering requirements in modern systems with RF bandwidth-limited signals, such as cellular, PCS and UMTS, usually demand lowpass-type selectivity. The standard DC-to-cutoff equi-ripple passband, however, is seldom required. Here, standard lowpass prototypes may be considered non-optimum or even wasteful in terms of an excessive passband width. Lowpass functions with a finite-interval ...
متن کاملOne 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...
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 کاملEvaluating Lowpass Filters for fMRI Temporal Analysis
Temporal filtering of fMRI images is an important part of the process of preparing the data for clinical examination. We are able to reduce noise accumulated from both exogenous and intrinsic sources during scanning by applying a filter to the time series. This paper summarizes the testing methods and results found from the evaluation of linear and non-linear temporal filtering methods used in ...
متن کاملExtensions of One-Dimensional Gray-level Nonlinear Image Processing Filters to Three-Dimensional Color Space
This paper describes the development of computer simulation models to evaluate the filter algorithms in different color spaces. The objective of this project is to study the extension of filters from a one-dimensional gray-level space to a three-dimensional color space. The principal task of this project was to conduct and evaluate mathematical extensions of filters and determine which combinat...
