Selected Methods of Signal Filtration and Separation and Their Implementation

Abstract

Selected methods of filtration and separation of signals and their implementation using digital signal processors are presented in this section. At the beginning of the chapter, there is discussion of classical finite impulse response digital filters and infinite impulse response digital filters. However, special attention is paid to lattice wave digital filters, which are excellent in implementation. Considered as modern digital signal processors are the lattice modified wave digital filters. Presented in the next section are infinite impulse response digital filters with linear phase, where there is discussion of the their causal realizations. In the following section, these are presented multirate circuits, circuits for reducing the sample rate–decimators, and circuits for increasing the sample rate–interpolators. Consideration is given to interpolator circuits based on lattice wave digital filters. After this a section dedicated to digital filter banks follows. Particular attention has been paid to digital filter banks useful for power electronics applications: wave digital filters, sliding DFT, moving DFT, and strictly complementary. There are presented some implementations of digital filters using digital signal processors. The last part of this chapter is devoted to selected digital signal processors.KeywordsField Programmable Gate ArrayCritical PathFilter BankDigital FilterDigital Signal ProcessorThese keywords were added by machine and not by the authors.
