[matlab] Predictive-coding-1 DL : 0: Basic communication theory requires that a minimum sampling rate of twice the frequency of the signal to be sampled will result in an accurate representation of the original signal. Because the human voice does not exceed 4000 Hz, a sampling rate of 8000 samples per second, or once every 125 microseconds, is used. The conversion process begins by analyzing each sample and converting it into an 8-bit word also called an octet. If there are 8 bits per sample and 8000 samples per second, then the product is 64,000 bits per second (64 kbps)—the digital voice channel.

[matlab] sample-theory-demo DL : 0: 抽样定理演示程序，能清楚看到当抽样速率大于2fs时恢复模拟信号的过程和当抽样频率小于2fs时频率混叠的过程。同时还包括频率抽样过程的演示。非常详尽。通过此演示程序，你肯定能明白抽样定理这一通信领域基本的原理！-The sampling theorem demo program, you can clearly see that when the recovery process of the analog signal sampling rate greater than 2fs and frequency aliasing when the sampling frequency is less than 2fs process. Also includes a demonstration of the frequency of the sampling process. Very detailed. Through this demonstration program, you can certainly understand sampling theorem this basic principle in the field of communication!

[matlab] Matlabvoice DL : 0: 通过计算机上的多媒体卡，按照下列过程进行声音信号的录制、处理和回放，观察处理前后的波形，同时比较声音信号处理前后的效果。 1、将录制的信号反褶以后播放（反褶以后的信号移到t=0点开始）。 2、将录制的信号改变取样率（相当于进行了尺度变化）以后播放。 3、将录制以后的信号延时1s，并将幅度降低一半，接着与原来的信号相加，然后播放。-Multimedia card on your computer, follow the process for recording, processing, and playback sound signal waveform observed before and after treatment, while comparative effectiveness sound signal before and after treatment. 1, the signal recorded after deconvolution player (deconvolution signal moves after t = start 0:00). 2, the signal is changing the sample rate recording (is equivalent to a scale change) later playback. 3, after the recorded signal delay 1s, and reduce the rate by half, and then with the original signal are added, then play it.
