NMR We want to make the logical design of the detection and correction module of a NMR structure.

1. Verify the logical expression of the error detection signal proposed in sub-section 18.5.3.

2. Find the logical function having three inputs (S1, S2 and S3) and three outputs (M 1, M2 and M3), and which identifies the failing module.

3. Determine the logical function of a 3-input voter, then a 4-input voter.
What use would be a 4-input voter?
