Answer 1

Correct answer is (a) 20 dB/decade Best explanation: The given filter is a first order Band Pass Filter. Also, the Roll-off of the filter is depends upon the order of the filter. For a first order it is 20dB/decade, for second order it is 40dB/decade, and so on. Therefore, the Roll-off of the filter = 20 dB/decade.
