针对光伏电池电路直流部分的MPPT算法所设计的PWM脉宽调制模型。(MPPT algorithm for the DC portion of the photovoltaic cell circuit design of the PWM pulse width modulation model.)

Plot the log-magnitude of the Fourier transform of the signal over the interval [0, π], using a 1024-point FFT. The signal should be windowed with a Hamming window of two different durations: 25 ms and 10 ms with the window placed at the signal’s center in each case. Show the log-magnitude plot for each duration.
