16.4.3. Frequency response<br />
The frequency response function allows monitoring the digital C/N levels for each DVB-T carrier. In<br />
fact the echoes can also be seen with the frequency response, but the interpretation is different.<br />
The following screenshot shows the frequency response for a near perfect DVB-T carrier, where all<br />
the carriers have a similar level, remaining almost hidden.<br />
The frequency response is almost fl at for all the carriers (6816 carriers for an 8k DVB-T) in the<br />
above screenshot. This means that the digital C/N for all the carriers is very good.<br />
The following screenshot shows the frequency response for a carrier with a delayed signal of 2us<br />
and with similar power than the main carrier.<br />
The above screenshot shows the typical behavior of the frequency response when a clear echo is<br />
present.<br />
