浅析有线电视质量指标级联累加计算式

A Brief Analysis on Cascade Accumulation Formula for Cable TV Quality Index

用通俗易懂的方法,分析两种有线电视质量指标级联累加计算式的原理和计算方法,指出传统的累加计算方法是基于对数及其逆运算的原理设计出来的;"K法"则是通过查表和"四则运算"来进行的,比较直观且简易,特别适合新入行者使用。

Simple analysis on two methods of calculating cable TV quality index with cascade accumulation shows that the classical method is based on logarithm and its reverse arithmetic,while‘K'method is a combination of table- lookup and fundamental arithmetic,is comparatively straight forward and easy to grasp for raw recruit.
