SECTION 6 DIGITAL FILTERS - Analog Devices
DIGITAL 6 DIGITAL FILTERS Finite Impulse Response (FIR) FILTERS Infinite Impulse Response (IIR) FILTERS Multirate FILTERS Adaptive FiltersDIGITAL 6 DIGITAL FILTERSWalt KesterINTRODUCTIOND igital filtering is one of the most powerful tools of DSP. Apart from the obviousadvantages of virtually eliminating errors in the filter associated with passivecomponent fluctuations over time and temperature, op amp drift (active FILTERS ), etc., DIGITAL FILTERS are capable of performance specifications that would, at best, beextremely difficult, if not impossible, to achieve with an Analog implementation. Inaddition, the characteristics of a DIGITAL filter can be easily changed under softwarecontrol. Therefore, they are widely used in adaptive filtering applications incommunications such as echo cancellation in modems, noise cancellation, andspeech actual procedure for designing DIGITAL FILTERS has the same fundamentalelements as that for Analog FILTERS .
analysis of stock prices, etc. The input samples, x(n) are passed through a series of buffer registers (labeled z–1, corresponding to the z-transform representation of a delay element). In the example shown, there are four taps corresponding to a four-point moving average. Each sample is multiplied by 0.25, and these results are
