- especially it is very much useful in high quality AUDIO applications because of its flat response in both pass band and stop band where as chebyshev will be useful in signal monitoring applications where the phase is not important criteria
- low pass filters are used to filter noise from a circuit .noise is a high freequncy signal, when passed through a low pass filter most of the noise is removed and aclear sound is produced

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.
What is the main characteristic of a Butterworth filter?
Butterworth filter works as an ideal low pass filter.Butterworth filter is best suited for the closed loop gain to be as close to 1 as possible within the passband.Roll-offs become steeper,they approach the ideal filter more closely.
What is the definition of m in m derived filters?
m in m derived filters refers to its association with the midpoint impedance
What is noise filter?
noise filters are used in electronics and electric curcuts to reduce the the noise level which the electric switching generats sometimes the are single phase and there are three phase also the most used noise filters are ssr emc filters

Applications of active and passive filters?
Applications of active and passive filters?They are used for signal conditioningThey can be used to bypass power supply.They can also be used in speaker crossover designs.
Are there any non-butterworth implementations of Linkwitz-Riley Crossover arrangement?
It depends on how you look at it; the Butterworth filter is probably the only filter with absolutely flat response in the passband, and the knees/slopes of the filters of the Butterworth filters add upp more or less perfectly at the crossover (for example in a loudspeaker filter). The Linkwitz-Riley is built up through putting two filters in cascade, and it has an absolutely flat passband. As soon as you find a filter that can be arranged in cascade and that has an absolutely flat passband; you're there! And when/if you're "there", you will probably come to the conclusion that the filter you found turned out to be a Butterworth... =/ Some might yell out: "what about ChebyshevII?" Well, that one does not have that smooth knee of the Butterworth, and it has the stopband ripple that has to be taken into account. Here's an idea: Throw together two Chebyshevs in cascade (series) and find a good motivation to why it's a good filter, and you can name it after yourself. Sick but true!
What are the different types of filter(electronic)?
You can have low-pass, band pass or high-pass filters. You can also have all-pass filters designed to provide a time-delay. Then you can have active or passive filters. Filters can be designed to give different types of reponse, the main ones being Butterworth, Chebyshev and Elliptical, with Bessel used for time-delay.
What are the applications of multilevel inverters?

How are compressed air filters used?
Compressed air filters, which are also known as in-line filters, serve the purpose of filtering contaminants, such as dust, oil and moisture, from air after it has been compressed. They are usually used in industrial applications.
