Question

Which of the following is correct about logic gates?

(a) Logic gates have one or more input signals and only one output signal

(b) Logic gates have only one input and output signal

(c) Logic gates are analogous circuits

(d) Logic gates have only one input and many output signals

This question was addressed to me in exam.

My question is from Digital Electronics and Logic Gates in section Semiconductor Electronics : Materials, Devices and Simple Circuits of Physics – Class 12

Answer 1

The correct choice is (a) Logic gates have one or more input signals and only one output signal

Best explanation: Logic gates are the basic building blocks of any digital system. A digital circuit with one or more input signals but only one output signal is known as a logic gate. All the other statements are not valid.
