    A NOT gate can be implemented by:

    A)  a single diode

    B)  two diodes

    C)  a single resistor

    D)  a single transistor

    Correct Answer: D

    Solution :

     In digital logic, an inverter or NOT gate is a logic gate which implements logical negation. An inverter circuit outputs a voltage representing the opposite logic-level to its input. Inverters can be constructed using a single NMOS transistor or a single PMOS transistor coupled with a resistor.
