Question

A multiplexer (MUX)
(A) is a parallel to serial converter
(B) is also known as data distributor
(C) can be used as a logic function generator
(D) switch the data from several lines to one line

Choose the correct answer from the options given below:

• A. (A), (B), (C) and (D)
• B. (A), (B) and (D) only
• C. (B), (C) and (D) only
• D. (A), (C) and (D) only

Hint:

A multiplexer can perform multiple functions, including data distribution and parallel-to-serial conversion.

Answer 1

The Correct Option is A

A multiplexer (MUX) is a digital switch with the following capabilities:
- Converts parallel data inputs into a single serial data output (parallel-to-serial conversion).
- Acts as a data distributor, directing one of several inputs to the output based on selection.
- Functions as a logic function generator, performing various logic operations based on selection line configuration.
- Switches data from multiple input lines to a single output line.
Therefore, options (A), (B), (C), and (D) are all correct.
Final Answer: \[ \boxed{\text{(1) (A), (B), (C) and (D)}} \]
