Two Dimensional Linear Phase Multiband Chebyshev FIR Filter

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...

Three different criteria for the design of two-dimensional zero phase FIR digital filters

A new error criterion for the design of FIR filters is proposed. Filters with relatively many free filter coefficients are designed using the Chebyshev, the WLS, and a new partitioned minimax error criterion and the performance of the filters is compared. A general and fast technique for the WLS design is also presented.

A new iterative WLS Chebyshev approximation method for the design of two-dimensional FIR digital filters

In this paper, based on Chi-Chiou’s weighted least-squares (WLS) Chebyshev approximation method which is for the design of one-dimensional (1-D) FIR digital filters with arbitrary complex frequency response, we propose a new iterative W L S Chebyshev approximation method for the design of two-dimensional (2-D) FIR digital Alters with arbitrary complex frequency response. Several design examples...

Optimal Design of Linear-Phase FIR Digital Filters with Very Flat Passbands and Equiripple Stopbands

Ahs~aet-A new technique is presented for the design of digital FIR filters, with a prescribed degree of flatness in the passband, and a prescribed (equiripple) attenuation in the stopband. The design is based entirely on an appropriate use of the well-known Rem&-exchange algorithm for the design of weighted Chebyshev FIR filters. The extreme versatility of this algorithm is combined with certai...
