| Distortions and 8-VSB |
|
The complex signal 8-VSB requires constant monitoring and adjustment as the power amplifier ages. Unlike NTSC, a DTV transmitter can produce full power with a modulated carrier and still leave some or all viewers without a picture, brought on by the cliff effect. These days, it is not just the amount of power produced but the quality of the transmitted signal.
