| 2 | =========================== |

| 3 | |
|---|
| 4 | key: cp:back&forw FFT filter |
|---|
| 5 | |
|---|
| 6 | Filters all traces of the display with a given FFT filter <filter> |
|---|
| 7 | twice. Before the second filtering the traces are time reversed |
|---|
| 8 | and the result traces are time reversed again. Thus eventual |
|---|
| 9 | phase shifts of the single filter operation are corrected by |
|---|
| 10 | the second pass. This routine DELETES the input traces ! Only |
|---|
| 11 | the result traces remain on the display. |

| 17 | Filter to be applied to the traces on display. |

| 20 | Example: |
|---|
| 21 | |
|---|
| 22 | DOUBLEFIL BP_2S4S ! applies the FFT filter BP_2S4S to the |
|---|
| 23 | ! traces on the display |
