Consider a circuit inside of the blackbox is given in fig. 1. Propose an "Experiment Design" that performs the
following requirements:
1) When all switches are in ON position, Vo will be -4V.
When any two switches are in ON position, Vo will be -2V.
When any one switch is in ON position, Vo will be -1.333V.
When all switches are in OFF position, Vo will be -1V.
2) Write down the final report that contains the detailed steps of your work.
