Programming

Consider the following circuit to control a moving walkway.Every 2 seconds, the circuit examines two weight sensors anddecides if the walkway will travel Northward or Southward or beturned off. There is a weight sensor in the North half of thewalkway and a weight sensor in the South half of the walkway. Ifboth sensors detect zero weight, the walkway is turned off. If thewalkway is off and both sensors detect weight, the walkway remainsoff. If the walkway is off and one of the sensors detects a weight,the walkway starts moving in the opposite direction, i.e., if theNorth weight sensor detects a weight, the walkway starts movingSouthward. Once the walkway is in motion, it retains that motionuntil both weight sensors detect zero weight.

a) What are the states for the circuit controlling thewalkway?

b) What are the inputs to the circuit and what values can thoseinputs have?

c) Draw the finite state table and finite state diagram for thiscircuit.

d) Identify one example scenario where you would want thecircuit's behavior to be different from what is specifiedabove.
