2. Non-recursive filter synthesis
As a general rule, there are four steps:
solving the approximation problem to determine the filter coefficients that satisfy a given frequency template;
choice of structure and quantization of filter coefficients into a finite number of bits ;
-
quantization of filter variables, i.e. choice of word length for :
entrance,
exit,
intermediate memories ;
simulation to check that the final filter meets the specified template.
Here, we focus on the first step. Step 4 is only necessary if steps 2 and 3 are implemented; however, the choice of a realization structure and quantification problems are not...
