If you … WebDesign FIR filter step by step impulse display standsWebWindowed FIR filters use the cutoff frequency as part of the design process, but the cutoff is specified before the windowing operation. For Windowed FIR filters of sufficient taps (more than 10 for a simple lowpass), the cutoff frequency has a magnitude near 0.5 (or 6 dB down). This magnitude varies slightly with the order and the window type. impulse direction nerve

"WebIn the default Windowed Sync filter, we have given some reasonable start values there for the filter order: 2 * cutoff freq for highpass and bandpass (for cutoff < 2Hz). 20 to 40% of cutoff freq for lowpass and 1 to 5 Hz for line noise bandstop. " - Fir windowed filter
