电视广播的迅速发展要求不断地提高电视设备的质量指标。精确而简便的测量技术不仅为生产部门所需要,对维护使用部门来说也是不可缺少的。目前,我国电视广播已经跨入彩色广播的新阶段,这对设备的指标和测量技术提出了更高的要求。电视测量技术内容很多,就电视通道的测量技术而论,主要包括:信号电平、线性失真、非线性失真、杂波、反射损 The rapid development of television broadcasting requires constantly improving the quality of television equipment. Accurate and simple measurement technology is not only required by the production department, but also indispensable for the maintenance department. At present, China’s television broadcasting has stepped into a new phase of color broadcasting, which sets higher requirements for the indexing and measurement technologies of the equipment. TV measurement technology, many, on the TV channel measurement techniques, including: signal level, linear distortion, nonlinear distortion, clutter, reflection loss
