Signal Filter

The Signal Filter Function applies a filter to a signal to allow frequencies above or below a certain threshold to pass through while attenuating other frequencies.

The Function implements Butterworth filters and supports three Filter modes:

Low Pass

All frequencies below the Cutoff Frequency (Low) will be allowed to pass through the filter.

Given a signal with a 10Hz and 20Hz component, a 15Hz cut-off will allow the 10Hz component through, while attenuating the 20Hz component.

High Pass

All frequencies above the Cutoff Frequency (High) will be allowed to pass through the filter.

Given a signal with a 10Hz and 20Hz component, a 15Hz cut-off will allow the 20Hz component through, while attenuating the 10Hz component.

Band Pass

This performs cascading low-pass and high-pass filters. All frequencies between the Cutoff Frequency (Low) and Cutoff Frequency (High) will be allowed to pass through the filter.

Given a signal with a 10Hz, 20Hz, and 30Hz component, a 20Hz cut-off (for both the Low and High) will allow the 20Hz component through, while attenuating the 10Hz and 30Hz components.

Details for an example and its configuration can be found in the How to Use section.
