Concept
Elliptic filters, also known as Cauer filters, are highly efficient in terms of achieving a sharp cutoff with minimal transition band by allowing ripples in both the passband and stopband. When comparing elliptic filters to other filter types like Butterworth and Chebyshev, elliptic filters provide the steepest roll-off for a given filter order, making them ideal for applications requiring precise frequency discrimination.
