QUESTION:
For the following circuit:
(a) Assume that the inverters have a delay of 1ns and the other gates have a delay of 2 ns. Initially A = 0 and B = C = D = 1, and C changes to 0 at time = 2 ns. Draw a timing diagram and identify the transient that occurs.
(b) Modify the circuit to eliminate the hazard.
ANSWER:
Step 1 of 5
(a) Given that,
The inverter delay = 1 ns
AND gate delay = 2 ns
OR gate delay = 2 ns
