Value	Meaning
TRUE	Insert the "Filter High Frequency" (003A,0221) element (that corresponds to this channel) into the dataset and then set its value.
FALSE	Delete the "Filter High Frequency" (003A,0221) element (that corresponds to this channel) from the dataset.

L_DOUBLE dHighFrequency

New filter high frequency.

Comments

This function sets the value of the "Filter High Frequency" (003A,0221) 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 High Frequency" (003A,0221) element that corresponds to this channel by setting bInclude to FALSE. In this case the dHighFrequency parameter is ignored.
