A. A/[1+ j(f/fo1)]x[1+ j(f/fo2)]x[1+ j(f/fo3)] B. A/[1+ j(f/fo)]3 C. A/A/[1+ j(f/fo1)]+ [1+ j(f/fo2)]+ [1+ j(f/fo3)] D. All of the mentioned.
Explanation: The gain equation for op-amp is AOL(f) = A/[1+ j(f/fo1)]x[1+ j(f/fo2)]x[1+ j(f/fo3)]. 7. Find out the frequencies that are avoided in frequency response plot?
