IIR filters have nonlinear phase characteristic which means the output of such a filter is (most likely) a deformed version of the input without the filtered frequency. On the other hand IIR filters might become unstable. So IIR filters are used, when the user is not particularly interested in the output in time-domain but only in frequency-domain, e.g. in audio applications such as speakers...

Difference between FIR and IIR filters?
1)The impulse response of an IIR filter extends over infinite duration while the impulse response of FIR filter is stricted to finite no. of samples. 2)IIR is not always stable but FIR is always stable. 3)FIR can have precisely linear phase while IIR filters do not have linear phase.
What are the applications of multilevel inverters?
The various applications of multilevel inverters are 1. Motor Drives 2.Active Filters 3.Power conditioning
What are air vent filters made of?
Air vent filters are typically made from materials such as fiberglass, pleated synthetic fibers, or foam. Fiberglass filters are inexpensive and effective at trapping larger particles, while pleated filters offer a greater surface area for improved filtration of smaller particles. Foam filters are often used in reusable applications due to their washable nature. The choice of material impacts the filter's efficiency, lifespan, and application suitability.
What is the frequency scaling technique in filters?
Frequency scaling in filters is a technique used to adjust the frequency response of a filter by altering the frequency components of the input signal. This can involve multiplying the frequency values by a scaling factor, which effectively stretches or compresses the frequency spectrum. As a result, the filter can be adapted to different applications without redesigning the filter itself, allowing for greater flexibility in signal processing tasks. This technique is commonly applied in digital signal processing to create filters with desired characteristics.
Why do we go for low pass filters?
Low pass filters are used for various purposes in different areas.
Explain the advantages and disadvantages of FIR filters compared to IIR counterparts?
IIR filters are recursive and FIR filters are non-recursive. Also FIR filters are linear phase and IIR filters are not; several applications are sensitive to non-linear phase (communications, medical, etc). In implementation, IIR filters require fewer taps (smaller order) and thusly are easier to implement and have fewer zeros. Also FIR filters are always stable, while IIR filters can often become unstable in implementation. The previous answer is correct about delays.
Where is the IIR filter used?
IIR Filter is one of the Digital Filters .it is used mostly in Audio Signals Processing
Difference between FIR and IIR filters?
1)The impulse response of an IIR filter extends over infinite duration while the impulse response of FIR filter is stricted to finite no. of samples. 2)IIR is not always stable but FIR is always stable. 3)FIR can have precisely linear phase while IIR filters do not have linear phase.
Why IIR filter do not have linear phase?
Infinite Impulse Response (IIR) filters do not have linear phase because their feedback structure introduces non-linear phase characteristics. Unlike FIR filters, which can be designed to have a symmetric impulse response leading to linear phase, IIR filters can exhibit phase distortions due to their recursive nature. This means that the phase response of an IIR filter is typically frequency-dependent, resulting in different phase shifts at different frequencies, which can lead to signal distortion.
Difference beyween IIR and FIR filters?
The impulse response of an IIR filter extends over infinite duration while the impulse response of FIR filter is stricted to finite no. of samples. Also IIR is not always stable but FIR is always stable.
What does it mean if a digital filter is IIR?
We can divide filters two types based on the length of the impulse resopnse 1. FIR where the impulse responce is finite 2. IIR where the impulse response is infinite
What is the difference between FIR and IIR filter?
1)The impulse response of an IIR filter extends over infinite duration while the impulse response of FIR filter is stricted to finite no. of samples. 2)IIR is not always stable but FIR is always stable. 3)FIR can have precisely linear phase while IIR filters do not have linear phase.
What are iir and fir?
IIR is infinite impulse response. FIR is finite impulse response.
