What is gain of Chebyshev filter?
Type-I Chebyshev Filters
In this band, the filter interchanges between -1 & 1 so the gain of the filter interchanges between max at G = 1 and min at G =1/√(1+ε2) . At the cutoff frequency, the gain has the value of 1/√(1+ε2) and remains to fail into the stop band as the frequency increases.
What do the Chebyshev II filters have?
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.
How do you find the order of a Chebyshev filter?
The order of a Chebyshev filter is equal to the number of reactive components (for example, inductors) needed to realize the filter using analog electronics.
What is the magnitude response of Chebyshev filter?
In the Chebyshev type-2 filter, you specify the frequency at which the stopband begins, and the maximum ripple amplitude. In Figure 14.26, we see the magnitude responses of N = 2–8, Chebyshev type-2 LPFs, with a stopband beginning at 1 rad/s and a stopband minimum attenuation of −50 dB.
