Practical Implementation of Digital Filters
Trevor J. Terrell · Palgrave Macmillan UK eBooks · 1988
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). These keywords were added by machine and not by the authors. This process is experimental and the keywords may be updated as the learning algorithm improves.
