EFFECT OF TRANSMISSION IMPAIRMENTS


ITU-T P.11 SPANISH-1993 发布历史

This Recommendation is concerned with the effect of transmission parameters, such as those listed above, on customer opinion of transmission quality. It is based on information contributed in response to specific questions which have been studied by the CCITT. Much of this information is based on the results of subjective tests in which participants have talked, listened or conversed over telephone connections with controlled or known levels of the impairments and rated the transmission quality on an appropriate scale. General guidance for the conduct of such tests is provided in Recommendation P.80. In addition, Recommendation P.82 provides guidance on the use of telephone user surveys to assess speech quality on international calls.

LabX秘技 | 仪器联用:质量自动传输

在绝大多数分析实验中尤其是定量分析,样品称量往往是一个分析实验室工作任务开始,质量传输伴随着整个实验过程。那么保证质量在不同测试阶段准确就变得尤为重要。实验做得很好,但是质量输入错误造成整个实验失败,结果超标,复核、调查、进入OOS、复验,最终结果发现只是把数字1输入成了7,你说冤不冤,就连CAPA都不好写呢。那么有没有一种更好方式来保证无误质量传输呢?有!...
