Given the following function, F=(AB)(A′B), find the time periods at which hazards occur and describe which type of hazard it is. Assume B=1 all the time and A=0 from 0 ns to 40 ns, A=1 from 40 ns to 80 ns, A= 0 from 80 ns to 100 ns, and A=1 for the rest of the time. Each gate has a propagation delay of 10 ns.
