Low Pass Filter

Hello Clark,

you should know what kind of LPF you need, respectively at least part of the intended characteristics, e. g. fc/fs (cut-off frequency/ sample rate), stop band attentuation or equivalent analog filter prototypes (butterworth, chebyshev, elliptical filters of nth order). Personally, I'm often using simple first oder LPF, box-car integrators or CIC decimation filters in signal processing.

Naturally, hundreds of books have been written about digital filters.

Best regards,

Frank
