A combinational switching circuit has four inputs and one


A combinational switching circuit has four inputs and one output as shown. F = 0 iff three or four of the inputs are 1.

   a.  Write the maxterm expansion for F.

   b.  Using AND and OR gates, find a minimum three-level circuit to realize F (5 gates, 12 inputs). Write the expression for F and attach a Word, PDF, or image file of your circuit.
