本文在忽略文献提出的WFFT数值积分误差和混迭误差的基础上,分析推导了泄漏误差的解析公式,并给出了利用两次WFFT的结果对信号的测量幅值、频率及相角进行校正的方法步骤及公式.
Based on ignoring the WFFT numerical integral error and aliasing error proposed in the literature, this paper analyzes and deduces the analytic formula of leakage error and gives the result of twice WFFT to correct the measurement amplitude, frequency and phase angle Method steps and formulas.
