Which one of the following is the advantage of FIR filter over IIR filter?

Which one of the following is the advantage of FIR filter over IIR filter? Correct Answer FIR filter can have an exact linear phase

FIR filtering has these advantages over IIR filtering:

1.It can implement linear-phase filtering. This means that the filter has no phase shift across the frequency band. Alternately, the phase can be corrected independently of the amplitude.

2. They are guaranteed to be stable.

3. It can be used to correct frequency-response errors in a loudspeaker to a finer degree of precision than using IIR Filter.

Note:

IIR Filters

FIR filters

1. IIR filters are difficult to control and have

no particular phase.

1. FIR filters make a linear phase always

possible.

2. IIR can be unstable.

2. FIR is always stable.

3. IIR filters are used for applications that are not linear.

3. FIR filters are dependent upon linear-phase characteristics.

4. IIR filters are dependent on both i / p and o / p.

4. FIR is dependent upon i / p only

5. IIR filters consist of zeros and poles and require less memory than FIR filters.

5. FIR only consists of zeros so they require more memory.
 

6. Where the system response is infinite, we use IIR filters.

6. where the system response is zero, we use FIR filters.

 

7. IIR filters are recursive, and feedback is also involved.

7. FIR filters are non-recursive and no feedback is involved.

A rotary drum filter with 30% submergence is used to filter concentrated aqueous slurry of calcium carbonate containing 15lb of solids per cubic foot of water. The pressure–drop is 2011Hg. If the filter cake contains 50% mixture (wet basis), calculate the filter area required to filter 10 gal/min of slurry. The filter cycle time is 5 min. The specific cake resistance depends on the pressure–drop as: α (ft/lb) = α (Δp)0.26, where α = 2.90×1010 Viscosity of the filtrate = 6.72×10-4 lb/ft-s. Density of calcium carbonate = 168.8 lb/ft3. Neglect filter medium resistance.
