Abstract :
In this paper, we show the results of laboratory measurements aimed at studying, under controlled conditions, different characteristics of notching in OPERA PLC modems, such as total and effective notch width, notch depth, maximum notch depth, etc. In addition to the laboratory measurements, we made field measurements that showed that the expected notch characteristics are also present in real PLC systems. Our measurements showed that notching is a useful technique to avoid interference with existing services.
