WebDesign second-order IIR notch digital filter. A notch filter is a band-stop filter with a narrow bandwidth (high quality factor). It rejects a narrow frequency band and leaves the rest of the spectrum little changed. Frequency to remove from a signal. If fs is specified, this is in the same units as fs. By default, it is a normalized scalar ... WebOct 23, 2024 · This still did not solve the problem because the problem is not due to truncation alone. The way I solved this problem was to use an anti-aliasing filter followed by down-sampling the input signal, followed my desired low-pass IIR filter. I understand that you are implementing a HPF, which is an LPF translated in frequency domain.
