Explanation: The cauer filter has a ripple pass band and a ripple stop band. So, generally cauer filter gives the best stop band response among the three. 7. Determine the order of filter used, when the gain increases at the rate of 60dB/decade on the stop band.
A. Second-order low pass filter
B. Third-order High pass filter
C. First-order low pass filter
D. None of the mentioned
Answer:A

A. Second-order low pass filter B. Third-order High pass filter C. First-order low pass filter D. None of the mentioned
Explanation: The gain increases for high pass filter. So, for a third order high pass filter the gain increases at the rate of 60dB/decade in the stop band until f=fL.
