An emergency stop system is to be designed for a certain automatic production machine. A single "start" button is used to turn on the power to the machine at the beginning of the day. In addition, there are three "stop" buttons located at different locations around the machine, any one of which can be pressed to immediately turn off power to the machine. (a) Write the truth table for this system. (b) Write the Boolean logic expression for the system. (c) Construct the logic network diagram for the system. (d) Construct the ladder logic diagram for the system
