Question

Which of the following combinations of logic gates can decode binary 1101?

• A. One 4-input AND gate
• B. One 4-input AND gate, one OR gate
• C. One 4-input AND gate, one inverter
• D. One 4-input NAND gate, one inverter

Hint:

To decode a specific binary pattern, AND gates are used for bitwise operations, and inverters may be added to modify the output.

Answer 1

The Correct Option is C

To decode binary 1101, a 4-input AND gate is used for logic AND operation on all bits, and an inverter is needed to invert the output to match the desired decoded value. Thus, the correct answer is One 4-input AND gate, one inverter.
