Abstract

The different power measurement techniques used for NTSC (peak envelope power) and HDTV (average power and peak-to-average power ratio) are described. A brief description of a digital data transmission system is included to show why the HDTV signal is noiselike in nature and how it can be measured. A new type of RF analyzer with the ability to statistically measure peak-to-average power ratio is presented. The Zenith/AT&T digital spectrum compatible high definition television (DSC-HDTV) data transmission system is currently one of the systems being evaluated for the consideration as a US broadcast standard. Examples of signal measurement for this system are provided
