Question 1:

Considering the Inverting Amplifier in firgure 1.8, compute the gain as a function dependent on R1=1KΩ and R2=4.7KΩ.

Consider the inverting amplifier circuit presented below:

The gain of the amplifier can be computed as follows:

Question 2:

Considering the Non-Inverting Amplifier in figure 1.14, compute the gain as a function dependent on R1=1KΩ and R2=1KΩ.

Consider the non-inverting amplifier circuit presented below:

The gain of the amplifier can be computed as follows:
