FIR Filters of Variable Length -Laboratory 4 of 12 for the Texas Instruments TMS320C5416 DSK.A self-teach application or college laboratory to allow the student to find out by practical experiment the answer to the following question: How many coefficients are required when implementing a FIR filter for clear division between one range and another?Different filter lengths may be selected and the effect heard.

这是一个对于多关键字排序的程序源码。本程序主要从一下入手 1、 伪随机生成的数据包含语文、数学、英语三科成绩。总成绩为语文、数学、英语三科成绩的和。学号按成绩数组的下标赋值，生成学生成绩记录，将该记录保存到txt文档中 2、 从上面的txt文档中读取数据到一个二维数组中，以便对学生信息进行处理 3、 在总分排序好的情况下，给出排序的优先关系，根据优先关系由低位向高位逐个关键字进行排序。 请点击左侧文件开始预览 ！预览只提供20%的代码片段，完整代码需下载后查看 加载中 侵权举报

本实验完成发光二极管的循环点亮实验，由于输入晶振为20M，分频得到count1信号，故每间隔约1S彩灯循环移位一次。 也可以外接32768hz的晶振经4060分频后的1HZclk输入，自己可以尝试改变实验，加以练习。 现象：可以看到流水灯-In this experiment completed the cycle of light-emitting diode light experiments, as a result of the importation of crystal for the 20M, sub-frequency signal received count1, so each interval of about 1S Lantern a cyclic shift. Can also be the external 32768Hz crystal oscillator frequency by 4060 after 1HZclk input, they can try to change the experiment, to practice. Phenomenon: we can see water lights
