摘要

二阶抽样是由Kohnlenberg(1953)提出的，Wang从平移不变性的角度重构了二阶抽样。本文研究了该采样方案对带通信号的稳定性，讨论了采样函数的一些性质，并给出了减少采样条件数的最优相移。

Second order sampling with optimal phase shift for band-pass signals

The second order sampling was proposed by Kohnlenberg (1953), and Wang rebuilt it on a translation invariance view point. In this paper, we study the stability of this sampling scheme for band-pass signals, discuss some properties of sampling functions, and give the optimal phase shift to reduce the condition number.
