The SDAIII-CompleteLinQ toolset calculates total, random and deterministic jitter (Tj, Rj and Dj), periodic jitter (Pj) and data-dependent jitter (DDj), which includes inter-symbol interference (ISI) and duty cycle distortion (DCD). The toolset includes three algorithmic methods based on dual-Dirac models for calculating and decomposing Tj, Rj and Dj. The document describes the three methods and explains the similarities and differences.
