i and ii, pls provide a correct answer and explain
(a) A freezer is configured to operate with the following events: The compressor (C) will be turned on when the door (D) is closed, and the temperature (T) is above the limit. The fans (F) will be turned on when the compressor (C) is on. The light (L) will be turned on if the door (D) is opened. The door (D) switch is a normally open (NO) push button switch. The temperature (S) switch is a NO temperature limit switch. (i) Construct Boolean equations to implement the operations of the freezer. (ii) Design a physical ladder diagram based on (a)(i).
