What is the difference between Chebyshev I and Chebyshev II filters?

the type I Chebyshev filter has ripple in the pass band and a flat stop band, type II is the opposite with a flat pass band and ripple in the stop band.

What are the types of Chebyshev filters define each and compare?

Chebyshev filters are nothing but analog or digital filters. These filters have a steeper roll off & type-1 filter (more pass band ripple) or type-2 filter (stop band ripple) than Butterworth filters. The property of this filter is, it reduces the error between the characteristic of the actual and idealized filter.

What are the distinguishing features of a Chebyshev filter?

What are the distinguishing features of a Chebyshev filter? It has a maximally flat response over its passband. It only requires inductors. It allows ripple in the passband.

Which analog filters have ripples in both passband and stopband?

Elliptic filter

The elliptic, or “Cauer” filter has a ripple in both the passband and the stopband, as shown in Figure 14.27(a).
