چکیده

We present a robust non-iterative algorithm to design optimal minimum phase digital FIR lters with real or complex coe cients. We derive (1) the discrete Hilbert transform (DHT) of the complex cepstrum of a causal complex minimum phase sequence, and (2) the minimum fast Fourier transform length for computing the DHT to achieve a desired coe cient accuracy.

Optimal design of real and complex minimum phase digital FIR filters

We present a generalized optimal minimum phase digital FIR lter design algorithm that supports (1) arbitrary magnitude response speci cations, (2) high coe cient accuracy, and (3) real and complex lters. The algorithm uses the Discrete Hilbert Transform relationship between the magnitude spectrum of a causal real sequence and its minimum phase delay phase spectrum given by Cizek. We extend the ...

Low latency IIR digital filter design by using metaheuristic optimization algorithms

Filters are particularly important class of LTI systems. Digital filters have great impact on modern signal processing due to their programmability, reusability, and capacity to reduce noise to a satisfactory level. From the past few decades, IIR digital filter design is an important research field. Design of an IIR digital filter with desired specifications leads to a no convex optimization pr...

Design of IIR Digital Filter using Modified Chaotic Orthogonal Imperialist Competitive Algorithm (RESEARCH NOTE)

There are two types of digital filters including Infinite Impulse Response (IIR) and Finite Impulse Response (FIR). IIR filters attract more attention as they can decrease the filter order significantly compared to FIR filters. Owing to multi-modal error surface, simple powerful optimization techniques should be utilized in designing IIR digital filters to avoid local minimum. Imperialist compe...

Optimal FIR and IIR Hilbert Transformer Design Via LS and Minimax Fitting

The usual way of the implementation of on-line discrete Hilbert transformers is the design of linear phase finite impulse response (FIR) filters. Recently, a method has been published for the design of infinite impulse response (IIR) Hilbert transformers as well. The paper introduces a new method for the design of both FIR and IIR Hilbert transformers, based on a parameter estimation method for...

Design of Equiripple FIR Filters Using a Feedback Neural Network - Circuits and Systems II: Analog and Digital Signal Processing, IEEE Transactions on

The weighted least squares design of FIR filters is implemented in terms of a feedback neural network. The proposed neural network is shown to converge to the global minimum in each iteration for the current weighting function, and as the weighting function is adjusted from iteration to iteration, an equiripple design is achieved. The approach is applicable to FIR filters with piecewise-constan...
