Digital Logic
Palindrome Detector
A circuit that determines whether an input sequence reads the same forward and backward.
Detailed Explanation
Palindrome detection compares elements from opposite ends. For a bit sequence, the first bit must match the last, second must match second-to-last, and so on. A 3-bit palindrome detector checks if bit[0] equals bit[2].
Hardware implementation might use shift registers to capture the sequence, then XOR pairs for comparison. The result is AND of all pair comparisons (all must match for palindrome).
