Computers use logic gates.
An aeroplane has a warning system that monitors the height of the aeroplane above the ground, whether the aeroplane is ascending or descending, and the speed of the aeroplane.
Input  Binary value  Condition 
Height
(H) 
1  Height is less than 500 metres 
0  Height is greater than or equal to 500 metres  
Ascending or Descending
(A) 
1  Aeroplane is ascending or in level flight 
0  Aeroplane is descending  
Speed
(S) 
1  Speed is less than or equal to 470 knots 
0  Speed is greater than 470 knots 
The warning system will produce an output of 1 that will sound an alarm (W) when either of these conditions apply:
Height is less than 500 metres and the aeroplane is descending
or
The aeroplane is descending and speed is greater than 470 knots.
Draw a logic circuit to represent the warning system.

Plastic pipes of various sizes are manufactured by heating the plastic and using pressure.
The manufacturing system uses sensors to measure the pressure (P), temperature (T) and speed (S) of production.
The inputs to the manufacturing system are:
Input  Binary value  Condition 
P  1  pressure is > 5 bar 
0  pressure is <= 5 bar  
T  1  temperature is > 200 degrees Celsius 
0  temperature is <= 200 degrees Celsius  
S  1  speed is > 1 metre per second 
0  speed is <=1 metre per second 
The system will sound an alarm (X) when certain conditins are detected.
The alarm will sound when:
Temperature is >200 degrees Celsius and the pressure is <= 5 bar
or
Speed is > 1 metre per second and an Temperature
