An Artificial Transmission Line Experiment to Show Signal Processing Methods

摘要

The traditional artificial transmission line can provide needed experience in interpreting data. Particularly, in laboratories, the high cost of microwave sources, slotted lines, and instrumentation calls for an economical demonstration of the principles of wave propagation. The traditional Leecher Line experiments are troubled with high voltage signal sources (safety aspects) needed for neon bulb displays that do not unnecessarily load the signal source. Further, numerical values are not easily obtained from that light-on, light-off technology. The experiment described can illustrate reflected waves, matching lines, and spectral estimates using Bayesian methods. If desired, time domain testing can be illustrated with pulse sources.
