TRANS FFT (Fast Fourier transform), or Spectral mode, is a
time-to-frequency conversion algorithm where X=Signal Frequency
and Y = Signal Magnitude. When TRAXALL is set to TRANS FFT, passage
data can be viewed in real time only.
Here, the unfiltered signal is represented by the white graph line; the
red line represents the same signal after enhancement by the TRAXALL
DSP (digital signal processor).
X = Signal Frequency Y = Signal Magnitude
