Will terrestrial broadcasting survive the HDTV standard?

Key analyses and specifications that the author asserts should have been part of the precertification process for HDTV systems are outlined. As part of the current precertification process, estimates for the channel and equipment impairments and the associated power penalties in the C/N (carrier-to-noise) are not required, the range of BER (bit error rate) for a given EFH (error free hours) is not specified, and the expected spectral spreading into adjacent channels due to the nonlinear power amplifier is hardly mentioned. The problems with the ATTC laboratory tests and field tests are discussed.<
