Phase Jitter in DTV Signals

Today's state-of-the-art TV test transmitters for digital TV provide signals fully complying with the European DVB (digital video broadcasting) standard and the U.S. ATSC (advanced television systems committee) standard. Featuring calibrated settings for each of these standards, the transmitters cover all parameters stipulated by the respective specifications.TV test transmitters must not only be capable of generating signals in conformance with international standards, but also of simulating unfavourable receive conditions to determine the limits of performance of DVB and ATSC receivers and demodulators. The ETSI Technical Report ETR290 specifies all parameters that may degrade DVB signal quality during modulation and transmission.
