26 mai 2021 · Digital signal processing filters can be implemented using both the infinite impulse response (IIR) or finite impulse response (FIR) approaches

What is IIR and FIR filters?
If the impulse response of the filter falls to zero after a finite period of time, it is an FIR (Finite Impulse Response) filter. However, if the impulse response exists indefinitely, it is an IIR (Infinite Impulse Response) filter.
Why is FIR better than IIR filter?
Stability: As FIRs do not use previous output values to compute their present output, i.e. they have no feedback, they can never become unstable for any type of input signal, which is gives them a distinct advantage over IIR filters.
Is Butterworth filter FIR or IIR?
