In a chemical factory, a chemical is stored in three different tanks. A level
sensor in each tank produces a positive input voltage (+24V) when the level of
chemical in the tank drops below a specified point. Ladder logic will monitor
the chemical level in each tank and indicate an alarm condition when the level
in any two of the tanks drops below a specified point.
Develop a Truth Table, the resulting Boolean Expression and ladder logic in
its simplest form. Explain your method of Boolean simplification.
Inputs Required:
Tank 1 sensor
Tank 2 sensor
(X0)

(X2)
Tank 3 sensor
Outputs Required:

Alarm
A given room has two push-button switches S1 and S2 that are used to control a light bulb (e.g., one switch near each door of a room with 2 doors) as shown in below. You are to design a logic circuit so that the bulb can be controlled (essentially, toggled) by either switch.a. Write down the above scenario in an IF-THEN condition format b. Develop a truth table for the above case c. Develop a minimized Boolean function in SOP form
This is the question:
Suppose that we want to synthesize a circuit that has two switches x and y. The required functional behavior of the circuit is that the output must be equal to 0 if switch x is opened (x=0 ) and y is closed (y=1); otherwise the output must be 1.
My friend sent me the answer which I will attach but I have no idea what is going on .. can someone please explain in detail?
