MATLAB generates filter coefficient groups

The filter coefficients generated by MATLAB can control gain, and the general normalization is to control gain of 1. The order of the filter is determined by the data rate, the transition bandwidth, the pass-band Ripple, and the overcast ripple.

After the fs,apass,astop is fixed, as long as the difference between fpass and fstop is certain, the order of the filter is certain.

In Altera's FPGA, the filter IP support multi-factor is a set of coefficients with the same number of orders.
