Logic Gates (CIE IGCSE Computer Science)

Consider the logic statement:

X = (((A AND B) OR (C AND NOT B)) XOR NOT C)

Consider the given logic statement:

X = ((NOT (A NAND B)) OR (B NOR C))

Consider the logic statement:

X = (((A NAND B) NOR (B AND C)) OR C)

Draw a logic circuit to match the given logic statement. 

All logic gates must have a maximum of two inputs. Do not attempt to simplify the logic statement

Consider the following logic statement:

X = ((B AND NOT A) XOR (A OR C))

Draw a logic circuit to match the given logic statement.

All logic gates must have a maximum of two inputs. Do not attempt to simplify the logic statement.

An alarm, Y, sends a signal (Y = 1) when certain fault conditions in a chemical process are detected. The inputs are:

The alarm, Y, returns a value of 1 if:

either temperature >= 120°C AND stirrer bar is OFF

or acidity > 5 AND temperature < 120°C

Draw the logic circuit for the above system using these logic gates.
