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

(X1)
(X2)
Tank 3 sensor
Outputs Required:

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?
a) Light in a two-story building is controlled by two switches. The top switch is
labeled Sj and bottom one is labeled S2. When a switch is “ON" the value is “1"
and when a switch is “OFF" the value is “0" The light goes "OFF" when both
switches are "ON" or both are "OFF". Draw the Truth Table of the lighting
system.
Write down the logic equation of the system in a SOP form
Implement the circuit of the lighting system using the SOP logic equation in
(b) using AND-OR gates
