Carry out all analyses before coming to the lab

• Use V_cc=9V
• Determine the output V_out in terms of the inputs V₁, V₂, V₃
• Build the circuit and verify the functionality. Make sure that V₁, V₂, V₃ are always connected to inputs in their respective valid ranges
• Try out the following
  1. V₃=0V, V₁=1Vcos(wt), vary V₂ and observe the output on the scope. What is a possible application of this arrangement?
  2. V₂=0V, V₁=1Vcos(wt), vary V₃ and observe the output on the scope.
  3. V₃=0V, V₁=V₂=2Vp(wt), where p(wt) is a triangular wave. Observe the output on the scope.
