Unformatted text preview: b. Latch is ____________________ sensitive. c. Flipflop is ______________________ sensitive. d. A multiplexer circuit has a number of ___________ inputs, one or more select inputs, and ________ output. e. Why is 2s complement better for implementing arithmetic logics than 1s complement? 2 of 2 3. (10 points) Show how the function can be realized using Act 1 logic blocks (Act 1 logic block is shown). Note that there are no NOT gates in the chip; hence complements of signals have to be generated using the multiplexers in the logic block. 4. (15 points) Complete the following timing diagram. 5. (15 points) Design a comparator logic circuit that compares two 4bit binary numbers ( A and B ). This comparator logic only has 1bit output (called AltB , A less than B). When A < B, AltB = 1 . Otherwise, AltB = 0 . i 4 i 5 i 8 f i 2 i 6 i 1 i 7 i 3...
