How to Select the Cutoff Frequency of Your Low-Pass Filter

WebA low pass filter is needed for most analog to digital converters (ADCs.) Without the filter, frequencies above half the sampling frequency of the ADC will "wrap around" into the sampled data. This is called "aliasing." For example, assume you have an ADC sampling at 20000 samples per second. Web23 jan. 2024 · Keep in mind that to convert frequency to index, you multiply by size and sampling frequency (divide by ram, rather than divide: def low_pass_filter (data, band_limit, sampling_rate): cutoff_index = int (band_limit * data.size / sampling_rate) F = np.fft.fft (data) F [cutoff_index + 1 : -cutoff_index] = 0 return np.fft.ifft (F).real
