一例特殊阻抗失配问题的分析宋午云＊在维护载波电路时，一般对于正常的阻抗匹配问题都非常重视，而有些阻抗失配，只有在特定的条件下方会显示出来，所以就难免疏忽，以致影响测试精度，或引起故障。现将在日常维护工作中，碰到的一例易被忽视的阻抗失配现象分析如下。１...
Analysis of a special case of impedance mismatch Song Xiaowun * In the maintenance of a carrier circuit, the impedance matching problem is generally very much valued for normal, and some impedance mismatch, only under specific conditions will be displayed, it is inevitable negligence, so that the impact Test accuracy, or cause malfunction. Now in the routine maintenance work encountered an overlooked impedance mismatch analysis is as follows. 1 ...
