3.
4.
The power of the 605 Hz tone only
The relative power of the data tones
with respect to the 605 Hz tone
The relative power of each data tone
with respect to the average power of
all the data tones

read, a data tone that is +2 dB greater
than the average will be displayed in
which of the following colors?
1. Cyan
2. Green
3. Yellow
3-45.
The phase error bar graph of the LMS-11
display what information about the
Link-11 signal?

2. Mean deviation of the phase error
only
3. Standard deviation of the phase error
only
4. Both the mean and standard
deviations of the phase error
3-46.

for a data tone will be represented on the
bar graph in which of the following
colors?

2. Green
3. Yellow
4. Red
3-47.
The LMS-11 will indicate that the data
received is bad if the standard deviation
falls in which of the following ranges?

2. A positive value greater than 45
degrees
3. A negative value less than 45 degrees
4. Both 2 and 3 above
