Description
This module implements FIR filters for the synchronous computational model.
Synopsis
fir :: (Fractional b, ProcType b, Pos s, Typeable s) => ProcId -> FSVec s b -> Signal b -> Signal b

fir :: (Fractional b, ProcType b, Pos s, Typeable s) => ProcId -> FSVec s b -> Signal b -> Signal bSource

All kinds of FIR-filters can now be modeled by means of fir. The only argument needed is the list of coefficients, which is given as a vector of any size. To illustrate this, an 8-th order band pass filter is modeled as follows.

 bp = fir "fir Id" $(vectorTH [0.06318761339784, 0.08131651217682, 0.09562326700432,
