What kind of FIR filters are needed?
FIRmaker FIR filters are non-symmetrical, complex-valued transfer functions. Despite their excellent performance they have a compact time behavior and a very smooth frequency response in both magnitude and phase. This, in turn, allows for implementation with a comparably low FIR tap count and low latency.
Currently, nearly every available DSP is capable of implementing the filters generated by FIRmaker.
