摘要
本文分析了采样信号的非均匀性对于能量／功率测量的影响，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能量／功率收敛于真值的条件。仿真结果验证了理论的正确性。
猅he influence of nonuniformly sampling on energy/power measurement is analyzed and the energy relation of the nonuniformly sampled signal in time domain and frequency domain is deduced. The convergence condition which energy/power is calculated with nonuniformly sampled signals is obtained. The simulation result agrees with the theoretical predictions.
