FIR Linear Phase Fractional Order Digital Differentiator Design using Convex Optimization
In this paper, design of linear phase FIR digital differentiators is investigated using convex optimization. The problem of differentiator design is first described in terms of convex optimization with different optimization variables’ options, taken one at a time. The method is then used to design first order low pass differentiators and results are compared with Salesnick’s technique and Park...
متن کاملStable IIR digital differentiator design using iterative quadratic programming approach
In this paper, we present an iterative quadratic programming approach to design stable IIR digital di!erentiator. At each iteration, the cost function is transformed into a quadratic form by treating the denominator polynomial obtained from the preceding iteration as a part of the weighting function, and the pole radii are constrained to lie in the unit circle by using the implications of Rouch...
متن کاملComputation of fractional derivatives using Fourier transform and digital FIR differentiator
In this paper, the computation of a fractional derivative using the Fourier transform and a digital FIR di!erentiator is investigated. First, the Cauchy integral formula is generalized to de"ne the fractional derivative of functions. Then the fractional di!erentiation property of the Fourier transform of functions is presented. Using this property, the fractional derivative of a function can be...
متن کاملDesign of Low Power and Area Efficient FIR Digital Filter
the impulse response can be either finite or infinite. The methods for designing and implementing these two filter classes differ considerably. Finite impulse response (FIR) filters are digital filters whose response to unit impulse (unit sample function) is finite in duration. This paper presents the design of low power FIR filter and area efficient parallel linear phase FIR digital filter. Lo...
