Overlay comparison of waveforms made at optimum replay-tracking setting, as well as at manually set left, center, and right replay-tracking positions. |
Differences in radio-frequency waveform are more evident when viewed using different replay-tracking settings. |
|
6c |
The examples in Figure 7 may help to determine what is a minor or a noticeable difference and at what point the difference is unclear. |
In Trial 1, the waveforms (a) and (c) in Figure 7 were incorrectly matched. |
|
6d |
Critically compare overlaid waveforms at various points along the tape to increase awareness of the range of variations. |
The shape of the radio-frequency pattern may fluctuate at various points in the recording. |
