Hamming Code Calculator

It means 7 total bits with 4 data bits and 3 parity bits. The code can correct any single-bit error within each 7-bit block.

Split your data into 4-bit blocks, pad the last block if needed, and encode each block separately. The tool outputs the full encoded bitstream.

No. Hamming (7,4) reliably corrects only one flipped bit per block. Two or more errors in the same block may go undetected or be corrected incorrectly.

The syndrome is the result of parity checks on received bits. A non-zero syndrome value equals the position of the flipped bit.

They add minimal overhead while allowing receivers to detect and automatically correct single-bit transmission errors without retransmitting the entire message.
