A factory produces two types of wood blocks with 2m and 4m lengths. The blocks are moved by a conveyor belt and passing under two photocells A and B spaced by 3m apart as shown in the following figure. The blocks are separated by more than 4m. A trap door is placed immediately to the right of photocell B. To separate the two types of blocks, it is required that the trap door should open when the small block pass under B and close when the blocks passed beyond B. The door opens when the output (2) of state machine is logic 1. The designer needs for . AND-gate(s) for implementing the aforementioned state machine
