BCD vs Binary: Identify the Valid Code
Binary-Coded Decimal bridges the gap between hardware arithmetic and human-readable seven-segment displays. The system receives six 4-bit data words: 0101, 1001, 1010, 1100, 1111, and 0000. Classify each 4-bit pattern as a valid BCD digit or an invalid BCD state. Determine the decimal equivalent for the valid codes and identify why the invalid codes fail the BCD specification.
Constraints
- Analyze each 4-bit word independently.
- Assume standard 8421 BCD encoding.
