HOW TO USE BACKWARD LINEAR PREDICTION

Backward linear prediction is a technique used for predicting several points at the begin-
ning of FID and replacing them. You can use it when the FID includes ringing. Moreover,
backward linear prediction can predict several points at the beginning of FID that were
missing in a measurement and extrapolate them. This method is used in measurements
with wide observation ranges such as multinuclear measurements.

The process starts.
■ Addition of data point
1.
Recall the data.
2.
Extrapolate the data as follows.
a.
Select PreTransform-Shift.
