Convolution engine for FIR and IIR equal?

1. Why does Conv () not work for IIR filters?
2. How do FIR filters compare to IIR filters?
3. Which filter is more stable FIR or IIR?
4. Which has faster response IIR or FIR filters?

Why does Conv () not work for IIR filters?

Since the IIR filter would need infinite coefficients, the convolution operator cannot be used to implement it in reality; instead, you would need to implement it as a difference equation.

How do FIR filters compare to IIR filters?

IIR filters are well suited for applications that require no phase information, for example, for monitoring the signal amplitudes. FIR filters are better suited for applications that require 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.

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.
