自己编写的，1024点快速傅里叶变换、倒频谱分析、功率谱分析及其Applet曲线显示程序源代码。 说明清楚，附有验证使用的数据文件-themselves prepared in 1024 point fast Fourier transform, cepstrum analysis, power spectrum analysis and Applet curve shows the source code. Make it clear with the use of the test data

这个函数用于估算光谱中的最大信息熵，它同时满足了倒频谱的局限和相关谱的局限-This function provides an ARMA spectral estimate which is maximum entropy satisfying correlation constraint (number of poles)and cepstrum constrains (number of ceros)

频谱分析 对频域信号中的各种谱线进行倒频谱求解-Frequency domain signal spectrum analysis of the various lines to solve the cepstrum

matlab环境下实现语音预处理 包括语谱图 倒谱系数 短时频谱的画图-voice pretreatment Matlab environment, including spectrogram drawing of the short-time spectral cepstral coefficients

常用信号分析程序，包括FFT，画包络谱，频谱，自相关、互相关，倒频谱，功率谱-Common signal analysis program, including FFT, painting envelope spectrum, spectrum, auto-correlation, cross correlation, cepstrum, power spectrum
