6 f) o: G( V5 R$ F1 GIn recent issues, Analog Dialogue has dealt extensively with topics in shielding and grounding,[1,2] emphasizing the techniques needed to protect the integrity and precision of analog signals in the dc and audio-frequency domain from inteRFering signals, whether at line frequency or at much higher frequencies. To complement those articles, we suggest here the elements of good practice for high-resolution “video speed” converters, i.e., converters of 10-bit or greater resolution, operating at word rates above 1 MHz/ b8 K# @1 g$ C: K

近几期的Analog Dialogue 着重对屏蔽和接地问题进行了广泛的探讨，强调这些技术在直流和音频范围内对保证模拟信号的完整，精确，免受工频或更高频率的干扰方面将起到作用。这里我们建议将本文中有益于高分辨率“视频”转换器，即10位或10位以上精度，字节速率在1MHz以上的方法作为对已发表文章的补充。
