Digital Filters for Low-Frequency Equalization

Document Thumbnail

Digital filters with high resolution in the low-frequency range are studied. Specifically, for a given computational power, traditional IIR filters are compared with warped FIR filters, warped IIR filters, and modified warped FIR filters termed warped individual z FIR filters (WizFIR). The results indicate that IIR filters are the most effective in a number of situations.
