Question

What type of multiplexing is used in serial buses?

(a) Time division multiplexing

(b) Code division multiplexing

(c) Frequency division multiplexing

(d) Phase multiplexing

This question was addressed to me in an online quiz.

I'd like to ask this question from Modulation and Multiplexing topic in division Introduction to Electronic Communication of Avionics

Answer 1

The correct option is (a) Time division multiplexing

For explanation: In serial buses, time division multiplexing is used to split the digital data, which is in binary numbers, into individual bits which occupy a particular time slot and is transmitted. The use of serial buses increases the limit on transmission speed and reduces noise.
