Using a time domain analysis method which is originally used in the derivation of a fractional delay filter, we find the derivations of these proposed filters are quite straightforward. By expanding the predefined ideal input and output signals of the filter into their Taylor series, we can approximate the desired filter with these Taylor series as input and output signals of a LTI system. After some simplification, we derive a set of linear equations which can be solved numerically for the filter’s coefficients. Aside form the derivations of these filters, this time domain analysis allows us to derive a Peano kernel for each proposed filter. A Peano kernel can represents the approximation error of the filter. Some designing examples are also demonstrated in this dissertation.口試委員會審定書 謝 i文摘要 iiBSTRACT iiiesign of Digital Integer order Differintegrator, Fractional Hilbert Transformer and Differentiator in Time Domain with Peano Kernel 1hapter 1 Introduction 1hapter 2 Fractional Delay Filter and Its Peano Kernel 4.1 Introduction 4.2 Derivation of Fractional Delay filter 5.2.1 Preliminaries 5.2.2 Derivation of Fractional delay filter 5.3 Peano Kernel of the FD system 7.4 Design Examples 8.5 Conclusion 11hapter 3 IIR Integer Order Differintegrator and Its Peano Kernel 12.1 Introduction 12.2 Derivation of Discrete Integer order differentiator and Integrator 12.2.1 Integer order Differentiator 12.2.2 Integer order Integrator 15.3 Derivation of the Peano Kernel 15.4 Design examples 17.5 Stability 19.6 Conclusion 20hapter 4 Fractional Hilbert Transformer and Its Peano Kernel 22.1 Introduction 22.2 Derivation of fractional Hilbert Transformer 23.3 Peano Kernel of the Fractional Hilbert transformer 26.4 Design examples 28.5 Conclusion 30hapter 5 Design of Discrete Fractional Differentiator with Peano Kernel 32.1 Introduction 32.2 Derivation of the Discrete Fractional Differentiator 33.2.1 Discretization of the fracional differentiation 33.2.2 System approximation with Taylor series 34.3 Peano Kernel of the fractional differentiator 36.4 Design examples 37.5 Conclusion 40hapter 6 Conclusion 41EFERENCE 45136 bytestext/htmlen-US整數微分/積分器希爾伯特轉換器分數積分器泰勒級數皮亞諾被積函數IIR filterfractional differentiatordifferentiatorintegratorHilbert transformerTaylor seriesPeano kernelthesishttp://ntur.lib.ntu.edu.tw/bitstream/246246/188365/1/index.html
