Value	Meaning
TRUE	Insert the "Filter Low Frequency" (003A,0220) element (that corresponds to this channel) into the dataset and then set its value.
FALSE	Delete the "Filter Low Frequency" (003A,0220) element (that corresponds to this channel) from the dataset.

Comments

This function sets the value of the "Filter Low Frequency" (003A,0220) element that corresponds to this channel. Set bInclude to TRUE to force the function to insert the element if it does not already exist in the dataset.

This function can also be used to delete the "Filter Low Frequency" (003A,0220) element that corresponds to this channel by setting bInclude to FALSE. In this case the dLowFrequency parameter is ignored.
