Moving Average filter

This filter smoothes the signal course by calculating the average of a specified number of mea-

sured values in a string of numbers. Due to average calculation, a change in distance becomes

increasingly visible.

Raw data

Data after filtering with Moving Average

and Moving Median

The higher the number of measured values per filter, the longer the response time of the sen-

sor. This means that a change in distance only becomes fully visible for the output after a delay.

Option 1: Select the required filter length from predefined filter lengths

The following selection options are available:

Value

Standard

High

Very High

Highest

Option 2: Enter the filter length as a numerical value

If the predefined filter lengths are not suitable, an individual filter length can be entered for the

Moving Average and Moving Median filters. Especially when it comes to applications without dy-

namic changes in distances, such as the verification of the position of an object, a greater filter

length can improve the performance of the sensor. You can specify the length of the Moving Av-

erage and Moving Median filters after selecting the Custom filter.

Moving Median filter: 1 - 21 values

Moving Average filter: 1 - 256 values

In the factory settings, the filter is set to Highest. In general, the more measured values per fil-

ter, the better the repeatability and the higher the reproducibility of the results.
