The circuit shown in figure converts
(The figure shows a logic circuit where the MSB passes directly to the output, and each subsequent output bit is the XOR of the current input bit and the previous output bit).
- A. BCD to binary code
- B. Binary to Excess-3 code
- C. Excess-3 to Gray code
- D. Gray to Binary code
Answer: D. Gray to Binary code
Explanation: The circuit diagram shows a cascade of XOR gates where the MSB is retained as is, and each subsequent bit is formed by XORing the current input bit with the previous generated output bit. This is the standard logic implementation for converting a Gray code to Binary code.
