State variables in lake ecosystems are subject to processes that act on different time scales. The relative importance of each of these processes changes over time, e.g., due to varying constraints of ...
The basic concepts underpinning time-domain reflectometry. Difference between frequency- and time-domain analysis. Some applications of TDR measurements. Time-domain reflectometry (TDR) is a technique ...
RF signals historically are measured using spectrum analyzers, at least that was before oscilloscopes offered sufficient bandwidth for those measurements. With oscilloscope bandwidths over 100 GHz, RF ...
A time domain reflectometer (TDR) measures reflections along a cable. It is similar in principle to radar. To measure those reflections, the TDR transmits an incident signal into the cable and watches ...
