Practical Implementation of Digital Filters

  • Trevor J. Terrell
Chapter

Abstract

Having selected or derived the desired digital filter pulse transfer function, G(Z), (see chapter 2 and chapter 3) and, furthermore, having determined the appropriate processor word length (see chapter 4), then the next step is to undertake the implementation of the filter’s linear difference equation corresponding to G(Z). This linear difference equation is used to compute the filter’s output y(n)T values, which will be a filtered version of the filter’s input x(n)T values (see figure 1.1).
