WebA low-pass filter is a filter that passes signals with a frequency lower than a selected cutoff frequency and attenuates signals with frequencies higher than the cutoff frequency. The exact frequency response of the filter depends on the filter design. The filter is sometimes called a high-cut filter, or treble-cut filter in audio applications. WebSep 5, 2015 · $\begingroup$ Firstly thanks geometrikal for answering. I did not really ask the question properly, so here goes again. I have my data and want to use a Gaussian LP filter at 50Hz say. Do I do this as follows: 0: FFT Signal data S(t) -> S(f) 1: Gaussian frequency resp for 50Hz LP as e.g. F(f) = exp(c(f-50)^2) 2: iFFT filter -> F(t) 3: shift and window …
