Double and triple exponential moving average band stop.

The double and triple band stops look to unstable for use because of the overshoot that can cause a strange behaviour.

They can be used, but in practise they look to strange for good results.

In the images we can compare the EMABS, DEMABS and TEMABS.

Result of EMABS(VALUE;1,5;1000)
Result of DEMABS(VALUE;1,5;1000)
Result of TEMABS(VALUE;1,5;1000)

To use DEMABS and TEMABS in Mover we do:



  • parameter1 is the value we want to filter.

  • parameter2 is the amount of samples/values used in one of the cutoff frequencies.

  • parameter3 is the amount of samples/values used in the other cutoff frequency.
