By minimizing a quadratic measure of the error in the passband and stopband, an eigenvector of an appropriate real symmetric and positive-definite matrix is computed to get the filter coefficients. Several IIR filters such as notch filters, Nyquist filters and partial response filters can be easily designed by this approach. Some numerical design examples are illustrated to show the effectiveness of this approach.application/pdf1643964 bytesapplication/pdfzh-TW國立臺灣大學電機工程學系暨研究所IIR 埃根濾波器FIR 埃根濾波器時域及頻域線性限制IIR EigenfiltersFIR EigenfiltersTime and Frequency Domain Linear Constraintsreporthttp://ntur.lib.ntu.edu.tw/bitstream/246246/7948/1/912219E002039.pdf
