S-Edit Views and T-Spice Simulation

Represent each NAND gate shown in the figure below with a symbol of your choice. Use these new symbols to design the circuit below and simulate it in T-Spice with all combinations of inputs. (The completed circuit need not have a symbol view).

Write down the truth table for the circuit. What logic gate does this circuit simulate?

Hand in a printout of the NAND gate (schematic and symbol view) and the complete circuit (schematic view). Also hand in your T-Spice code and output plot.
