Digital basic circuits

AND Gate

AND gate is a two input and one output circuit.

If both inputs of the AND gate are high/1 then the output is high/1 Else output is Low/0.

Let we name one of the inputs as A and other as B. Let we also name the output as X then;

Truth Table

Input A---- Input B----- output X
low/0 ------low/0 ------low/0
low/0 ------high/1 ------low/0
high/1------low/0 ------low/0
high/1------high/1------high/1


OR Gate

OR gate is also a two input and one output circuit.

If any one of the inputs is high/1 then the output is high/1 Else output is Low/0

Let we name one of the inputs as A and other as B. Let we also name the output as X then;

Truth Table

Input A---- Input B----- output X
low/0 ------low/0 ------low/0
low/0 ------high/1 ------high/1
high/1------low/0 ------high/1
high/1------high/1------high/1
