QUESTION $2$

Regarding a non$-$inverting amplifier based on an Operational Amplifier $($OA$)$ as shown in Figure $2,$ reason properly which of the following statements are true and which are not, considering a non$-$ideal OA $($answers without proper reasoning or explanation will not be considered valid$)$:

a$)$

The closed$-$loop gain of this amplifier depends exclusively on the resistances R$1$ and R$2.$

b$)$

The unity gain configuration in a non$-$inverting amplifier maximizes the available bandwidth.

c$)$

The slew rate of the OA limits the amplifier's ability to follow high$-$frequency signals without distortion.

d$)$

In a non$-$inverting amplifier, the input signal is applied directly to the non$-$inverting input of the OA$.$
