DADiSP / Filters

Digital Filter Design Module   Updated 

DADiSP/Filters is a menu-driven module for FIR and IIR digital filter design and analysis. From any DADiSP Worksheet, you can quickly design, view and analyze both FIR (Finite Impulse Response) and IIR (Infinite Impulse Response) filters. Once you have designed a filter, you may filter the raw data, then view and analyze the filtered signal. Through the easy-to-use dialog boxes or simple one line functions, you can tune the filter iteratively, re-filtering the data until you have separated the signal from the noise cleanly.
