Contemporary logic circuits use MOSFETs as the elements ... You guessed it, diodes can also be used to build logic gates, but not all of them, only the AND and OR gates can be built using diodes ...

‘NOT’ If input A is ‘high’ then output Q ... then output Q will be ‘high’ Truth table for an ‘AND’ gate: A ‘1’ in a truth table represents where the input or output is ...

Computers use electrical circuits which have two states – on or off. This can also be represented as 1 or 0 or True and False. Logic gates take an input of True or False and give an output of ...
