Analysis of Low Pass IIR Digital Filter Design
Digital Differentiator is a vital signal processing tool. It is found in many applications, from low frequency biomedical equipment to high frequency radars. New developing fields such as touch screen tablets and online signature verification also has digital differentiators as basic building block. A approach is proposed to design approximately linear phase infinite-impulse-response (IIR) digi...
متن کاملAn approach to Digital Low-Pass IIR Filter Design
The paper describes the design process of discrete network – digital low-pass filter with Infinite Impulse Response (IIR filter). Based on given parameters that network should meet, and with the use of HDL hardware description language and MATLAB software package, hardware implementation of the filter transfer function was designed. Simulations confirmed the validity of the implementation desig...
متن کاملLow 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...
متن کاملDesign of Higher Order Digital IIR Low Pass Filter Using Hybrid Differential Evolution
In this paper, hybrid technique with differential evolution (DE) method as a global search technique and binary successive approximation (BSA) based evolutionary search method as a local search technique is proposed. Evolutionary search is used for the exploration and pattern search method for exploitation. To initiate with good population, the opposition based learning strategy is applied. Mig...
متن کاملDigital IIR Filter Design Using Differential Evolution Algorithm
Any digital signal processing algorithm or processor can be reasonably described as a digital filter. The main advantage of an infinite impulse response (IIR) filter is that it can provide a much better performance than the finite impulse response (FIR) filter having the same number of coefficients. However, they might have a multimodal error surface. Differential evolution (DE) algorithm is a ...
