132 FTB-5600

Use an Appropriate Spatial Smoothing Filter Value

Below is an example of applying different filter values to a same trace. The

first curve has a filter of 100 m applied to it. The noise is quite visible and

the PMD changes are sharp. Attempting to take measurements on this

trace without a filter is not recommended, as there is too much noise.
