Question

The AND function can be used to ___________ and the OR function can be used to _____________

(a) Enable, disable

(b) Disable, enable

(c) Synchronize, energize

(d) Detect, invert

I have been asked this question in an interview for job.

My question comes from Logic Gates and Networks topic in chapter Boolean Algebra and Minimization Techniques and Logic Gates of Digital Circuits

Answer 1

Correct answer is (a) Enable, disable

Explanation: The AND gate and OR gate are used for enabling and disabling respectively because of their multiplicity and additivity property. The AND gate outputs 1 when all inputs are at logic 1, whereas the OR gate outputs 0 when all inputs are at logic 0.
