Low Pass Filter

Hello Clark,

for the Quartus software, filters are a DSP application among others. An IIR filter e. g. is just a few lines of HDL code, some constants, registers, mutipliers and adders. Additionally, Altera supports certain filter types with IP cores (Megafunctions): FIR filter, CIC decimation and interpolation, and applicaton specific filters, e. g. for video processing. But you may also use open cores from the internet, HDL code examples usually given in digital filter textbooks or code generated by particular filter tools as well.

Regards,

Frank
