Explanation: The open loop gain of the op-amp AOL(f) is a complex quantity and is expressed as AOL(f) = A/[1+ j(f/fo)] . The remaining equations are expressed in polar form. 8. Determine the difference between two AOL(f) at 50Hz and 500Hz frequency? (Consider the op-amp to be 741c)
A. 40dB
B. 30dB
C. 20dB
D. 10dB
