非均匀采样对信号有效值测量影响的分析

The Influence on Effective Value Measurement with Nonuniformly Sampled Signals

本文分析了采样信号的非均匀性对于有效值测量的影响，推导了非均匀采样信号在时域与频域上的能量对应关系，得出了利用非均匀采样序列计算信号的有效值收敛于真值的条件，仿真结果验证了理论的正确性。

The influence on effective value measurement due to nonuniformly sampling is analyzed and the energy relation of the nonuniformly sampled signal in time domain and frequency domain is deduced.The convergence condition which effective value is calculated with nonuniformly sampled signals is obtained.Simulation agrees with the theoretical predictions.
