2. Design a four-bit combinational circuit 2's complementer.
(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?
