Symmetrical Bandpass Raised and Root Raised Cosine Filters

If low frequency filtering of a data stream is necessary, arithmetically symmetrical Raised and Root Raised Cosine Filters will eliminate Inter- Symbol Interference, (ISI), while at the same time provide for low frequency filtering.  FilterSolutions supports such filtering in its FIR filter suite. The rounding of the filter is controlled by the "Alpha" variable, just as in low-pass filters. At the value, Alpha = 0, we see a theoretically perfect brick wall, and at Alpha = 1, a completely round top.
