数字电视整体转换中信号调整的测量和分析

The Measure and Analysis of the Conversion on DVB-C

通过对数字电视整体转换中信号调整的测试数据进行分析和研究,对整体转换后HFC网络中信号指标的变化提前做出判断,科学、合理地进行信号的测量和网络的维护。

The thesis analyzes the test data of signal adjust over the conversion on DVB - C, then makes a theory investigation. Through a predicted judge on the HFC network signal change after the conversion, the thesis presents a more scientific and reasonable signal measurement and network maintenance.
