CHEBYSHEV APPROXIMATION FOR NON - RECURSIVE DIGITAL FILTERS by James H . McClellan

Implementation structure of 3-D FIR digital filters based on the transformation method

In this paper, we show the application of Chebyshev structure proposed by McClellan and Chan for design of three-dimensional (3-D) filters based on the McClellan transformation. We consider the implementation of 3-D FIR cone-shaped filters designed recently by Mollova and Mecklenbräuker. The Chebyshev structure is originally developed for 2-D digital filters designed by transformation method, b...

Performance of Complex Chebyshev Approximation in Delay-root-nyquist Filter Design

Root-Nyquist filters are crucial components in data communications and recently the ability to attach fractional sample delay attributes to them has become very important. Here we explore the application of Chebyshev approximation to design of such filters. Special attention is paid to the use of the Karam-McClellan algorithm, a fully complex extension of the well-established ParksMcClellan alg...

All-Pole Recursive Digital Filters Design Based on Ultraspherical Polynomials

A simple method for approximation of all-pole recursive digital filters, directly in digital domain, is described. Transfer function of these filters, referred to as Ultraspherical filters, is controlled by order of the Ultraspherical polynomial, ν. Parameter ν, restricted to be a non-negative real number (ν ≥ 0), controls ripple peaks in the passband of the magnitude response and enables a tra...

Design Algorithms for Doppler MTI and Filters (Using Chebyshev Approximation)

Robust Vibration Suppression in Flexible Payloads Carried by Robot Manipulators Using Digital Filtering of Joint Trajectories

In this paper, a method for suppressing residual vibrations in flexible payloads, carried by robot manipulators, is proposed and experimentally demonstrated. The proposed method is based on the preconditioning of the robot joint trajectories using FIR digital filters. Several classes of FIR filters such as: a) Parks-McClellan, b) Window-based methods (using Hamming, Hanning, Boxcar, Kaiser, Bar...
