利用Blackman窗函数对工频信号进行加窗FFT后校正计算出基波和谐波的幅值、频率和初始相角。-Blackman window function using frequency signal windowed FFT is calculated after the correction of fundamental and harmonic amplitude, frequency and initial phase angle.

用窗函数（矩形窗、汉宁窗、海明窗和布莱克曼窗）法设计FIR数字滤波器-Using the window function (rectangular window and hanning window, hamming window and blackman window) method to design FIR digital filter
