《遥测技术》1984年第一期和第四期先后刊登《对采样定理的一个小修正》(下简称《小修正》)和《关于采样定理》两篇讨论文章,对低通型时域采样(也称取样、抽样)定理(下简称采样定理)中最低采样频率f_S是大于等于还是必须大于信号最高频率f_C的2倍提出了不同的意见。借此讨论机会,笔者也谈谈对采样定理的学习体会。由于笔者手头可参考的资料不多(下面引用的
“Telemetry” in 1984, the first and fourth issue has published a “small correction on the sampling theorem” (hereinafter referred to as “small correction”) and “on the sampling theorem” two discussion articles, low-pass time-domain sampling (Also known as sampling, sampling) theorem (hereinafter referred to as the sampling theorem) the lowest sampling frequency f_S is greater than or equal to or greater than the signal maximum frequency f_C 2 times put forward different views. To discuss the opportunity, I also talk about the learning experience of sampling theory. Due to the small amount of information I can refer to on hand (quoted below)
