Web26 mar. 2024 · 2 Answers Sorted by: 34 Look at the filter function. If you just need a 1-pole low-pass filter, it's xfilt = filter (a, [1 a-1], x); where a = T/τ, T = the time between samples, and τ (tau) is the filter time constant. Here's the corresponding high-pass … Web30 apr. 2016 · On the simplest level, a highpass filter is just a filter (sometimes called a low-cut) that attenuates low frequencies below a certain cutoff frequency and allows frequencies above to pass.

WebA lowpass filter is supposed to let in low frequencies and elimiate high frequencies. So the wikipedia version looks right to me- for a low frequency, dT should be big, for a high frequency it should be small. However, I'd really suggest either hiring someone who knows DSP or doing some more research before blindly implementing a filter.
