What Is The Difference Between Butterworth Chebyshev I And Chebyshev II Filters?

What Is The Difference Between Butterworth Chebyshev I And Chebyshev II Filters? Chebyshev II filters have the same advantage over Butterworth filters that Chebyshev filters have—a sharper transition between the passband and the stopband with a lower order filter, resulting in a smaller absolute error and faster execution speed. What is the main difference between
