advantages of fir and iir filters

PDF	IIR and FIR filters Some of the advantages of FIR filter are linear phase both recursive and non recursive stable and round off noise can be made smaller Some of the

Is FIR better than IIR?
FIR (finite impulse response) filters are usually more stable than IIR (infinite impulse response) since they don't have a feedback loop.
If you need linear phase response, you would probably have to use a FIR.
Why are FIR filters more stable?
In contrast, FIR filters are always stable because the FIR filters do not have poles.
You can determine if pole-zero pairs are close enough to cancel out each other effectively.
Try deleting close pairs and then check the resulting frequency response.
A FIR has equal delay at all frequencies while the IIR filter time delay varies with frequency.
A FIR filter has equal time delay at all frequencies, while the IIR filter time delay varies with frequency.
Usually the biggest time delay in the IIR filter is at the cut off frequency of the filter.

What are disadvantages of IIR filters?

5 IIR filter disadvantages
This can cause unwanted noise and distortion in the output signal.
Another disadvantage of IIR filters is that they can introduce phase distortion and nonlinear phase response, which can affect the quality and accuracy of the signal.

Advantages and Disadvantages of FIR and 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.

The good of IIR: • The IIR filter is better than the FIR in that it can

The IIR filter is better than the FIR in that it can produce the same response using fewer delay blocks (so uses less of the processor resources) The bad of IIR: IIR filters can become unstable For an impulse response, the output of an FIR will always settle back to 0
