摘要
检测运动员在运动中的心跳频率可以为教练员提供运动员的运动强度、训练效果判断依据,通过分析原始心跳信号样本的频谱,确定设计相应滤波器的各项参数,利用最大误差最小化准则设计了最优化FIR滤波器。用Matlab进行原始心跳信号样本滤波的仿真实验,实验结果显示滤波效果良好。
The criterion, which the coach exterminates the athletes＇ exercise intensity and exercise effect, is provided by detecting the heartbeat frequency, the parameters of the filter are decided by analyzing the frequency spectrum of the original heart signal, the optimized FIR filter is designed with the method of minimizing the maximum error. The simulating experiment of filtering the original heart signal is carried out with the Matlab program, the result of the experiment shows the effect of the filtering effect is excellent.
