What are the advantages and disadvantages of elliptic filter?

Answer 1

advantages:

1. It has a sharp cut-off and narrow transition width.

2. The frequency response specifications can be satisfied by a lower order filter.

3. Due to presence of zeroes unlike butterworth, chebyshev, it can effectively notch out frequencies.

disadvantages:

1. It has ripples both in passband as well as stopband.

2. It has a highly non-linear phase response in passband especially near band-edge.

3. Design and implementation is complicated.

Answer 2

Advantages of elliptic filters include having steeper roll-off rates and a more compact design compared to other filter types. Disadvantages can include higher sensitivity to component variations, leading to potential tuning and manufacturing challenges.
