Introduction:
In this lab, we reviewed the techniques of Superposition, the Thevenin's equivalent theorem, and using LTSpice code.
Task 1:
In
Task 1, for the circuit provided, shown in Figure 1, we needed to use
the Superposition technique to solve for all the voltages and currents,
as shown in Figure 2. The Spice code also needed to be used to verify
the results as shown in Figures 3 and 4.

Task 2:
In
Task 2, for the circuit provided, shown in Figure 5, we needed to use
the Thevenin's Equivalent technique to solve for the time delay,
as shown in Figure 6. The Spice code also needed to be used to verify
the results as shown in Figures 7 and 8.

Discussion:
By
completing this lab we were able to determine that the hand calculation
matched with the simulations. This lab helped with reviewing the techniques of Superposition, the Thevenin's equivalent theorem, and using LTSpice code
