3.) Describe steps required to complete this project:
1. Build the non-inverting amp(amplifier) and trace the input and output signals
using oscilloscope. Vin = 1Vpp, Ri = 1kohm, Rf = 10kohm.
2. Rebuild the circuit using Rf = 4.7kohm, Ri = 1.2kohm. calculate Acl and Vout.
3. Supposing Rf = 15kohm, Ri = 1kohm and Vin = 0.5Vpp, calculate Acl and Vout.
4. Build the inverting amp trace the input and output signals using oscilloscope.
Vin = 1Vpp, Ri = 1kohm, Rf = 10kohm.
5. Rebuild the circuit using Rf = 5kohm, Ri= 1.2kohm. calculate Acl and Vout.

Vout.
7. Verify the function of the voltage follower by tracing the input and output
signals using an oscilloscope. Use two difference input values.
8. Referring to step4, calculate the possible values for Rf and Rin if Vin = 0.5Vdc and Vout = 5Vdc.
