A negative feedback amplifier has an open-loop gain of 60,000 and a closed-loop gain of 300. If the open-loop upper cutoff frequency is 15 kHz, choose the closed-loop upper cutoff frequency. Also, calculate the total harmonic distortion with feedback if there is 10% harmonic distortion without feedback.

A certain op amp hasa unity-gain bandwidth of $f_{t}=15 \mathrm{MHz}$, If this op amp is used in a noninverting amplifier having a closed-loop de gain of $A_{0 C 1}=10,$ determine the closedloop break frequency $f_{B C}$. Repeat for a de gain of 100
