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 are the applications of Butterworth filters?
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 criterialow 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
What is the nature and characteristic of the electric fields?

What are the advantages and disadvantages of UJT?
The advantages of a UJT include low cost, a negative resistance characteristic, and a low value of triggering current. The main disadvantage is the inability to provide decent amplification.

What is the advantage of capacitor filter over inductor filter?
An inductive filter is in fact an LC circuit in which an inductor is connected in series with the capacitor. This arrangement is also known as a low-pass filter. http://www.answers.com/topic/inductive-filter
What is another name for a low pass filter?
Butterworth filter
How would one explain a butterworth filter?
The Butterworth Filter is a signal processing filter that is very renowned for things such as being able to solve "Impossible" math equations and doing things that would normally trouble a human.
What is the difference between the Butterworth filter and the Chebyshev filter?
The phase linearity of the Butterworth is better than that of the Chebyshev. In other words, the group delay (derivative of phase with respect to frequency) is more constant with respect to frequency. This means that the waveform distortion of the Butterworth is lower. Of course, with a single input frequency, there is no waveform dostortion in either filter. Another point to consider; the Butterworth filter is completely defined mathematically by 2 parameters: Cutoff frequency and number of poles. The Chebyshev filter has a third parameter: Passband Ripple.
Advantages and disadvantages of butterworth filter?
Advantage is that it has the most flat passband meaning that it is very good at simulating the passband of an ideal filter. The disadvantage is that it has a horrible stopband because it gradually goes to zero so some parts of the stopband are still passed. However, for an nth-order Butterworth Filter, as n increases, the closer it is to an ideal filter. However, it is highly impractical to build a ridiculously high order Butterworth filter.
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 characterictics of Roman architecture?
The Roman theatres were heavily inspired by the architecture of the Greeks. There are several characteristics of Roman theatres. These characteristics the foundations, the Roman concrete construction, and the semi-circular design.
