The operation of the channels (in this and the next chapter) is clarified with the example input signal of fig. 5.1.a. It consists of a small wanted channel, a slightly stronger adjacent channel and two much stronger far-off interferer channels that could cause intermodulation components in the wanted channel. At the output of each conditioning channel, only the digitized wanted channel is available with a specified
SINAD
and sample rate (fig. 5.1.b). As a starting point, a channel with full-analog conditioning is discussed. Further on it serves as a benchmark for the power/performance ratio of digitized channels.
