简易FIR滤波器
1、FIR数字滤波器的设计(1)在主函数中调用dsnFIR函数,滤波器参数设为21阶、带阻、矩形窗、采样率1000Hz、上下截止频率分别为100Hz,400Hz;(2)利用drawFIR函数分别画出所设计的FIR滤波器的幅频特性图和相频特性图。2、FIR数字滤波实现(1)编写一个输入信号子程序func(),输入信号为一连续函数,表达式为;(2)对输入信号进行采样,即 ,这里取采样率,得到离散序列x(n);(3)取x(n)中前40个点的值,将其转为复数存入复数数组x[64]中,并对x[64]做64点的FFT,得到的X(k)存回x[64]中;(4)已知在主函数中调用dsnFIR函数后得到的输出结果b[21]即为FIR滤波器单位冲激响应h(n)的值,将其转为复数存入复数数组h[64]中,并对h[64]做64点的FFT,得到的H(k)存回h[64]中;(5)已知用FIR滤波器对输入信号进行滤波就是将输入信号x(n)与滤波器单位冲激响应h(n)做卷积运算,故我转到频域采用FFT方法实现对输入信号x(n)的滤波,即将X(k)与H(k)相乘,得到滤波后信号的FFT变换Y(k),然后只需对Y(k)做IFFT变换即可得到滤波后信号y(n)。

Through the MP (on behalf of one of P I) of high 4 to control, AA `BB`
通过MP(代表其中一个P口)的高4位来控制,AA`BB`-4,5,6,7脚。12细分,没行数组里面分4对,每对数第一个加到P口控制电流方向,第二个数控制通电时间。正转AA`-BB`-A`A-B`B,数组由1到12行的读取,反转B`B-A`A-BB`-AA`,数组由12到1行的读取。参数POWER表示电机启动还是不启动,DIRECT参数表示方向,SPEED表示速度等级,每项通电时间用数组中的植/SPEED。本程序没考虑要走多少步的情况,调用一次就走一步。-Through the MP (on behalf of one of P I) of high 4 to control, AA `BB`-4,5,6,7 feet. 12 segments, no line inside the sub-array of four pairs, each of the P added to the number of the first current direction of population control, the second time the number of control power. Are transferred AA `-BB`-A `AB` B, the array from 1-12 line read, reverse B `BA` A-BB `-AA`, array 12-1 by the line read. POWER express motor parameters activated or not activated, DIRECT express direction parameter, SPEED express speed grades, each time power array sik/SPEED. This procedure did not consider how to go step-by-step situation, call a step away.
