讲述了MATLAB的图形的画法，对初学者和编程序想要产生对比图形的很有帮助(This PPT tell the way of drawing a picture in matlab)

双极性NRZ基带信号经带宽受限信号后造成码间干扰影响的眼图(Bipolar NRZ baseband signal is limited by the bandwidth of the signal resulting from the inter-symbol interference effects eye)

对光纤系统中的NRZ时域和频域特性进行了描述，值得一看(fiber NRZ system of time-domain and frequency domain characteristics of the description of an eye-catcher)

说明：  卡尔曼滤波器，可以对所得到的数据进行平滑，matlab源码(Kalman filter can be obtained by smoothing the data, matlab source)

两个图像的峰值信噪比（psnr）计算公式 归一化系数计算 dwt嵌入数字水印(PSNR of two images (psnr) formula normalized coefficients dwt Watermarking)

语音增强结果评价框架，其中包括四种语音质量评价方法：信噪比SNR，分段信噪比segSNR，对数谱失真LSD，PESQ。还包括生成设定信噪比语音文件的m文件。也适用于其他领域的语音质量评价。(The speech enhancement results evaluation framework, including the four speech quality assessment method: the SNR signal to noise ratio, segment the SNR segSNR, and the number of spectral distortion of LSD, the PESQ. Also includes the generation of m-files to set the signal to noise ratio voice files. Also applies to other areas of speech quality assessment.)
