WebThis is a compact fixed point 2nd order IIR filter implementation. The data and coefficients are short int types and the accumulator is of type int. The coefficients need to be scaled … WebMay 18, 2024 · If you allow large numbers in the accumulator, then you can make a first-order low-pass filter with one multiplication and some right-shifts. out = accum >> k accum = accum - out + in. Choose 'k' to change the cutoff frequency. The more shifts, the lower the low-pass cutoff, but the larger the value in the accumulator.
