Consider a sequential circuit that implements the following function in a self-driving car. Every second, the car's position within the lane is determined with cameras and fed as input to the sequential circuit. Accordingly, the car's steering wheel is moved to one of 2 positions: Left, Right. The car's position can be "Middle of a lane", "Drifting to the right edge of the lane", and "Drifting to the left edge of the lane". If the car is in the "Middle", the steering position is left unchanged. If the car is drifting to one of the edges of the lane, the steering is moved away from the edge, i. e., steering should be moved right if the car is near the left edge of the lane.
a. What are the states for the circuit controlling the steering?
b. What are the inputs to the circuit and what values can those inputs have?
c. Draw the finite state table and finite state diagram for this circuit.
