→‎Resync: Peak Detect
=== Resync: Peak Detect ===
Line up traces so peak (either max positive or max negative) within some given range of points all aligns.
 
For each trace the following must hold or the trace is rejected:
-- * (1-valid limit) < (peak value from candidate trace) / (peak value from reference) < (1+valid limit)-- * If 'valid limit' is 0 then this is ignored, and all traces are kept.
=== Resync: Resample based on Zero-Crossing ===
=== Sum of Difference ===
Minimize the 'Sum of Absolute Difference' (SAD), also known as 'Sum of Absolute Error'. Uses a portion of one of the traces as the 'reference'. This reference is then slid over the 'input window' for each trace, and the amount of shift resulting in the minimum SAD criteria is selected as the shift amount for that trace. 
See [[Sum of Absolute Difference (SAD) Pre-Processing]] for more information.
