FIR filter

Enables multi-tapped filtering of the current selection. A dialog box allows to enter the filename containing the weights for each tap.

For unity gain, the sum of the weights should equal 1.

For example, the following filter is similar to a 1 second RC filter but without the phase lag:

Table 7-4. FIR 1 second RC filter

0.06
0.09
0.1
0.15
0.2
0.15
0.1
0.09
0.06
This command destroys the original data in the selection of the trace!
