design a logic program that will track the activity for one turnstile. there will be three inputs PHASEA, B and RESET. there will be no output. the program should be able to track 999 total guests. turnstile the two switches, phase a and b that are mounted so that as a guest passses through the turnstile the two switches will turn on in a seqwuence. the sequence depends on whether the guest is entering or exiting the park. when someone enters the gate PHASEA outputs a signal before switch PHASEB. When someone leaves PHASEB outputs a signal before PHASEA. since the two switches are located close togetherk, there wil always be some overlap in their pulse outputs unless a guest starts through a gate and then backs out. if guest backs out, it wil create a false trigger that should not be counted.
