我正在使用此功能:
matplotlib.pyplot.specgram(x, NFFT=None, Fs=None, Fc=None, detrend=None, window=None, noverlap=None, cmap=None, xextent=None, pad_to=None, sides=None, scale_by_freq=None, mode=None, scale=None, vmin=None, vmax=None, hold=None, data=None, **kwargs)
我想绘制以250 Hz采样的信号的频谱图。默认情况下,此功能在0-125 Hz范围内绘制。我想将其更改为1至124 Hz。我该怎么办?
