How to Use
Step-by-step instructions
- 1Enter 4 bits of data (e.g., 1011).
- 2The calculator will generate the 7-bit Hamming code.
Hamming(7,4)
Adds 3 parity bits to 4 data bits to allow correction of single-bit errors.
Code = p1 p2 d1 p4 d2 d3 d4Variables:
p1Parity for bits 1, 3, 5, 7p2Parity for bits 2, 3, 6, 7p4Parity for bits 4, 5, 6, 7Example
Data 1011
Inputs:
Data:1011
Steps:
- 1.d1=1, d2=0, d3=1, d4=1
- 2.p1 = (1+0+1)%2 = 0
- 3.p2 = (1+1+1)%2 = 1
- 4.p4 = (0+1+1)%2 = 0
- 5.Code = 0110011
Result:
0110011
