E xample:
Suppose that the video carrier level in a channel, for instance the 45,
is of 25 dBmV, from the diagram we can deduce that the measurement
range is of 45 dB.
Thus, if when we carry out the measurement the C/N ratio is 54 dB the
display will show.
on the other hand, if C/N=42 dB we will see on the display:
