类比讯号(英语:analog signal)是指在时域上数学形式为连续函式的讯号。与类比讯号对应的是数位讯号,後者采取分立的逻辑值,而前者可以取得连续值。类比讯号的概念常常在涉及电的领域中被使用,不过经典力学、气动力学(pneumatic)、水力学等学科有时也会使用类比讯号的概念。
如果这真是个类比讯号,又有这么强大的脉冲,很可能其中有什么重要的讯息。
If it's really an analog signal with an impulse of such magnitude, it might contain information of importance.
这指的是数位转换器,它可以让类比电视机接收和播放数位电视讯号。
These would be the digital converter boxes that will enable analog TV sets to receive and display digital TV signals.
我们使用讯号对杂讯和失真比当作设计规格而非讯号杂讯比是因为,讯号对杂讯和失真比是讯号杂讯比和总谐波失真的集合,也是类比数位转换器动态效能完整的测量。
We use SNDR instead of SNR as our specification because SNDR is a combination of the SNR and the THD specifications and it is an overall measure of ADC dynamic performance.
