Analysis and Measurement of RF System Reflections and DTV Transmission


Terrestrial digital television (DTV) broadcast employs complex transmission facilities composed of filters, diplexers, transmission line components, and antennas. The reflections introduced by these components are minimized by broadband design methods, and the nature of the total reflection as these components are combined into a system is developed. The radio frequency (RF) transmission line, immitance, and network parameters used to characterize these systems (i.e., voltage standing wave ratio or VSWR) are related to key DTV performance parameters.
