相干采样与采样窗口

资料介绍
摘要:快速和超高速数据转换器的动态性能评估的最有用的技术之一是一致的采样。这种技术提高了快速傅立叶变换(FFT)的光谱分辨率和消除某些条件得到满足时的抽样窗口的需要。然而,如果不能满足相干采样条件,采样窗口可以使用。本应用笔记比较窗口采样相干采样,并提供了一个解释如何评价高速模拟 - 数字转换器(ADC ) ,使用这两种方法,同时详细介绍各的优点和缺点。

APPLICATION NOTE 1040
Coherent Sampling vs. Window Sampling


Abstract: One of the most useful techniques for evaluating the dynamic performance of fast and ultra-fast data
converters is coherent sampling. This technique increases the spectral resolution of a Fast Fourier Transform
(FFT) and eliminates the need for window sampling when certain conditions are met. However, if the
conditions for coherent sampling cannot be met, window sampling can be used. The following application note
compares cohere……
