取样定理在实际低通条件下的推广

Extension of the Sampling Theorem on the Practical Low-Pass Conditions

本文详细分析了在实用低通条件下的取样原理、输出的恢复号及其原信号的误差,以及低通特性的设计与取样频率的设置之间的关系。

The paper analyses fully the Sampling Theorem, the restoring signals of out-put and it's errors compared with the primary signals on the practical Iow-pass conditions. The paper puts forward the connection between the errors and the most common Iow-pass charecters, and also the relationships between the designs of the Iow-pass Charecters and the setting values of the sampling frequencies.
