Web5 ott 2008 · Filtering describes the act of processing data in a way that applies different levels of attenuation to different frequencies within the data. A high pass filter will apply minimal attentuation (ie. leave levels unchanged) for high frequencies, but applies maximum attenuation to low frequencies. Web15 ago 2015 · This spectra seems to agree that the bandpass filter is really a low pass filter. The high-low filters do seem to work. They seem a bit off with respect to the cutoff values specified. Overall I think these filters are for image processing. If you need filters for signal processing then look up ButterworthFilterModel or analogue filters.

WebFiltering can be used to condition time series data in multiple ways: High-pass filters remove low-frequency (slow) noise and pass high-freqency signals. Low-pass filters remove high-frequency noise and thus smooth the data. Band-pass filters allow only certain frequencies and filter everything else out Notch filters remove certain frequencies
