Question

what are logic gates?

Answer 1

a logic gate is an idealised or physical device implementing a boolean function that is it performs a logical operation on one or more binary inputs and produces a single binary output.

Answer 2

Logic gate is an electronic circuit in which the investment signals are located. (input signal) is one or more but the output signal is the only one.

Signals issued from these circuits are only available, while some logic conditions are satisfied between the input signals.

$\bf \: Therefore, \: they \: are \: a \: l ogical \: connection \\ \bf between \: the \: digital \: circuit , \: \\ \bf \: whose \: investment \: and \: the \: issued \\ \bf \: signals \: are \: called \: logic \: gates$

Logic gates are basically of three types

(i) OR gate or their gate

(ii) AND gate and and gate

(iii) NOT gate or gate (NOT gate)
