(The output generates the 2's complement of the input binary number.) 3. Construct a 5-to-32-line decoder with enable by using 3-to-8 and 2-to-4-line decoders with enables 4. For the decimal-to-BCD encoder given in the text (Slide 33 of chapter 5), assume by error that the 6 input and the 3 input are both HIGH. What is the output code? Is it a valid BCD code? 5. Construct a 16 x 1 multiplexer with 4 x 1 multiplexers. Use block diagrams. 6. Your tool box contains only NOR and OR gates and decoders. Using a minimum of these components implement the following functions: b. 7. Implement the following Boolean function with a (8X1) multiplexer: (a) (b) 8.
