pcm
- 实现了对模拟信号的量化编码并计算了模拟信号的量化噪声-The realization of the analog signal and the quantization coding to calculate the quantization noise analog signal
DTMF5410
- DTMF 编解码器在编码时将击键或数字信息转换成双音信号并发送,解码时在收到的DTMF 信号中检测击键或数字信息的存在性.采用ccs2.2开发。运行在DES5410APP-U开发版上。 子程序_start_ac01，完成AD 及DSP 的多通道缓冲串口（McBSP）初始化。 子程序_iir_to_dtmf，通过由函数set_freq_coff()初始化的系数，分别迭代运算产生行 频和列频，该子程序计算出的两个频率信号样本值分别放入累加器a 和b，相加之 后作为新的一个音频样本发送

yinpingshiyan
- 分别取长度N=160和N’=N+K的矩形窗函数作用于语音信号上，首先对其进行中心削 波，比较削波前和削波后语音信号波形，并使得削波后的信号进行乘积并求和，计算延迟为0<K<160时的相关值，并且用得到的相关值来检测语音信号的基音周期，用MATLAB画出图形。 -Length N = 160 were taken and N = N+ K rectangular window function in the role of the speech signal, the f
yuyinMFCCjuli
- 提取语音信号的MFCC特征参数，计算三段语音的匹配情况，并计算它们的MFCC距离-MFCC feature extraction of speech signals, computing the matching of three sections of the speech, and calculate their distance MFCC
KELAMO
- 验证克拉默不等式，也就是使得无偏估计量的方差达到一个下限。这时就要首先得到一个随机的无偏估计量，然后计算出其方差并绘制图形，最后绘制克拉默的界限图。-Verify Cramer inequality, which is so unbiased estimators of variance reaches a limit. Then we must first obtain a random unbiased estimator, then calculate its variance and g
