Retrospective: Historical Briefs From Past Issues

The July 1999 Journal published in: “DTV Transmitter Installation Experience and Planning” by David A. Sparano: “The advent of ATSC digital television (DTV) in the US. has created the need to install an entirely new terrestrial transmission infrastructure nationwide…the broadcast engineer will face a wide variety of challenges brought about by the requirement to install and maintain a second full-power television transmitter. There will be technical challenges, such as the need to adapt to a new transmission format, 8-vestigial sideband (8-VSB), with its unfamiliar performance parameters and measurement techniques. There will also be the physical challenge of installing a large, complex, transmitting system–oftentimes at an NTSC site where space and electrical power were at a premium even before the advent of DTV…The first major task facing the broadcast engineer is that of selecting a transmitter with the appropriate transmission technology for their particular application. There are two major transmission technologies employed in high-power DTV transmitters today: vacuum tube amplifiers and solid-state amplifiers.”
