Final answer:
A 4-bit to 1-bit multiplexer can be used to implement the 2-input NAND function by connecting the input signals to the appropriate select lines of the multiplexer.
Step-by-step explanation:
A 4-bit to 1-bit multiplexer can be used to implement the 2-input NAND function by connecting the input signals to the appropriate select lines of the multiplexer. The truth table for a 2-input NAND gate is:
ABY001011101110
To implement this using a 4-bit to 1-bit multiplexer, we can connect inputs A and B to the two select lines of the multiplexer, and connect inputs 0 and 1 to the two data lines. The output of the multiplexer will then correspond to the output of the NAND gate.
