Is IIR better than FIR?
The advantage of IIR filters over FIR filters is that IIR filters usually require fewer coefficients to execute similar filtering operations, that IIR filters work faster, and require less memory space. The disadvantage of IIR filters is the nonlinear phase response.
Which has faster response IIR or FIR filters?
Therefore, an IIR filter can provide a significantly faster and more efficient filtering operation than an FIR filter. You can design FIR filters to provide a linear-phase response.
Which filter is more stable FIR or IIR?
FIR filters are more stable as here the present output does not hold any relationship with the previous output. But IIR filters are less stable as it makes use of previous output samples as well. FIR filters need greater processing power in comparison to IIR filters.
