对原始语音进行上采样和下采样，分析对比他们的时域图和频谱图。最后对比原始语音、75HZ激励、150HZ激励以及噪声激励下的效果(SOME SIMPLE MANIPULATIONS OF SOUND USING DIGITAL SIGNAL PROCESSING The original sound and its spectrogram Downsampling the waveform downsampling Upsampling the waveform Linear filtering the waveform Original speech The source-filter model of speech Speech with 75-Hz excitation Speech with 150-Hz excitation Speech with noise excitation)

计算信噪比，计算公式是信号能量比上噪声能量(SNR Calculation，signal power divide noise power)
