Example:
In the color map based on the linear color curve, the range from -100
dBm to -60
dBm
is covered by blue and a few shades of green only. The range from -60
dBm to
-20
dBm is covered by red, yellow and a few shades of green.
Figure 11-4: Spectrogram with (default) linear color curve shape = 0
The sample spectrogram is dominated by blue and green colors. After shifting the color
curve to the left (negative value), more colors cover the range from -100
dBm to
-60
dBm (blue, green and yellow). This range occurs more often in the example. The
range from -60
dBm to -20
dBm, on the other hand, is dominated by various shades of
red only.
