音频信号降采样程序 支持48k->8k 24k->8k 8k->1k 的降采样.实现方法,先做低通滤波,再做采样点抽取.低通滤波起使用67点FIR,系数由matlab使用窗函数法生成 (Audio signal down-sampling procedures to support the 48k-)

数字移动:图中的九个点上,空出中间的点,其余的点上任意填入数字1到8.1的位置固定不动,然后移动其余的数字,使1到8顺时针从小到大排列.移动的规律是:只能将数字沿线移向空白的点. (Digital Mobile: Figure in the nine points, empty out the middle point, the rest of the points fill any position of the numbers 1 to 8.1 fixed and then move the rest of the figures, and make 1-8 clockwise from small to large array . The law of movement is: can only move along the number of blank spots.)

用VC6.0编写的对话框程序，可以读取ECG（txt格式）数据，并画图。采用差分阈值法对心电信号进行R波的检测并显示R波检测的个数，效果较好。程序中也编写了一个滤波器对心电数据进行滤波。(VC6.0 prepared by the dialog box procedure, you can read ECG (txt format) data, and drawing. Differential threshold method ECG R-wave detect and display the number of R-wave detection, the better. The program also write a filter for filtering the ECG data.)

两个设备形成对射，当有人通过时，一台设备发出指令，控制别的设备。(Two devices formed on the radio, when someone passed a device to issue commands to control other devices.)
