A lter is a system that can be used to modify or reshape the frequency spectrum of a signal according to some prescribed requirements. Generally, the purpose of most lters is to separate the desired signals from undesired signals or noise. A digital lter takes an input sequence of numbers and produces an output sequence of numbers. The lter design is a set(More)
| Elliptic rational functions have been traditionally derived from the Jacobi elliptic functions that are com-putationaly intensive. In this paper we construct the elliptic rational function, in the closed form, bypassing mathematical theory of special functions. We build the knowledge of the elliptic rational function using simple algebraic manipulations ,(More)
This paper is dedicated to Professor Radoslav Horvat on the occasion of his 80th birthday and the 50th anniversary of his scientiic work Abstract| We present an original software for continuous-time lter design. We have written this software in Matlab as a toolbox which we call afdesign. The afdesign toolbox is based on original numerical procedures. The(More)
Wind power can offer an economic and environmentally friendly alternative to conventional methods of power supply, and is especially suitable for remote off-grid locations. This paper focuses on the design of a wind energy conversion system that consists of a rectifier, a DC-DC converter, and a smart controller that maximizes the capture of wind energy,(More)
| This paper reviews the basic deenitions of a l-ter design. It introduces straightforward procedures to map the lter speciication into the design space, i.e. a set of ranges for parameters that we use in the lter design. We search this design space for the optimum solution according to given criteria, such as minimal Q-factor or minimal quantization error.(More)
This paper presents an extensible framework for the simultaneous constrained optimization of multiple properties of digital IIR lters. The framework optimizes the pole-zero locations for behavioral properties of magnitude and phase response, and the implementation property of quality factors , subject to constraints on the same properties. We formulate the(More)
