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 that can perform various functions:
- Parallel to serial conversion: It converts multiple parallel data inputs to a single serial data output.
- Data distributor: It can distribute one of several inputs to the output based on selection.
- Logic function generator: It can be configured to perform different logic operations by appropriately setting its selection lines.
- Switching data: It switches data from multiple lines to a single output line.
Thus, all options (A), (B), (C), and (D) are correct.
Final Answer: \[ \boxed{\text{(1) (A), (B), (C) and (D)}} \]
