1. Show by means of a timing diagram how a glitch could occur at the output of a two input NOR gate when the input changes from 01 to 10
2. Each bit in a binary word is stored in a flip-flop, how many flip-flops will be complemented when the number below is increased by adding 1
11011011
3. Implement the function below with an 4 x 1 multiplexer
EITHER DO QUESTION 4A OR QUESTION 4B BUT NOT BOTH
4A. A 3-bit finite state device, built with J-K flip-flops, has the following flip-flop input functions.
Draw the State Diagram
What are the unused states ?
Is the device self correcting ?
4B. A 3-bit finite state device, built with J-K flip flops, has the following repeating state sequence
3,7,1,2,4,6......
Find the simplified flip flop input functions
5. Implement the following function using a 3 x 8 decoder and one additional logic gate.
6. Give the binary string for both the next and the previous number in the Gray Code sequence
