The function firSY implements a FIR-filter for the synchronous computational model. All kinds of FIR-filters can now be modeled by means of firSY. 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 = firSY (vector [0.06318761339784, 0.08131651217682, 0.09562326700432, 
                     0.10478344432968, 0.10793629404886, 0.10478344432968, 
                     0.09562326700432, 0.08131651217682, 0.06318761339784 ])
