6. Using the Sum-of-Products circuit construction algorithm of Unit 07 and section 4.4.2 of the text book, design a circuit using only AND, OR, and NOT gates to implement the following truth table (if you can think of a circuit that uses fewer gates submit is as well for 2 bonus marks BUT you must use the circuit construction algorithm first): (5 marks) a b output 0 0 1 0 1 1 1 0 1 1 1 0 This operation is called NAND (for Not AND) and it can constructed using a single gate, as shown in Fig 4.17(a) of the text book. You dont have access to a NAND gate so you must construct it from AND, 0R and NOT gates. You may draw a circuit diagram by hand, use the lab software or Visio and embed the image in your assignment document. Keep in mind though that you may want to practice drawing circuit diagrams by hand because you may well have to draw one to answer an exam question. Note that the diagram MUST be very neat for full marks.
