Explanation: The rate at which the gain of the filter changes in the stop band is determined by the order of filter. So, for a low pass filter the gain decreases at the rate of 20dB/decade. 6. Which among the following has the best stop band response?
A. Butterworth filter
B. Chebyshev filter
C. Cauer filter
D. All of the mentioned
