Analysis-of-sound-signals

主要完成跳频通信中多音干扰模块的实现，采用了simulink搭建。(Complete the implementation of multi-tone interference in frequency hopping communication module, using simulink structures....)

数字信号处理matlab实验用FFT做谱分析源代码，可放心使用(Experiment with digital signal processing matlab FFT spectrum analysis to do source code can be freely used)

SVM MATLABSVM MATLABSVM MATLABSVM MATLAB(Support Vector Machine SVM and nuclear assembly MATLAB function)

选用DB小波对故障电力信号进行分解，从图中可轻易判断出故障点。(DB wavelet used to decompose the fault signal power, from the figure can easily determine the point of failure. )

The morphology operation to read the image and convert the rgb2gray, and convert in to the binaring the input image.Adding the binary noise to the image next the input image to make text in white and background in black. Next do the two operation dilation and erosion.

PCF transponders memory maps.
