代码说明:

  对于一个含有明显噪声的心电信号进行卡尔曼滤波处理,最大程度地 “还原”信号,达到去除噪声的目的。卡尔曼滤波(看成维纳滤波的一种实现方法)的特点如下: a) 是根据上一状态的估计值X(n-1)和当前状态的观测值Z(n)推出当前状态的估计值X(n)的滤波方法,不需要用过去的全部观测值。 b) 它是用状态方程和递推方法进行估计的,因而卡尔曼滤波对信号的平稳性和时不变性不做要求。 c) 使用全部观测值保证平稳性。(Kalman in matlab,if you need it,please download it.)

  • IJERTV1IS7260
    DC power is steady and continuous, with an electrical charge that flows in only one direction. When the output of DC power is represented on a graph, the result would be a straight line. AC power, on the other hand, flows back and forth in alternating directions so that, when represented on a graph, it appears as a sine wave, with smooth and regular peaks and valleys. A power inverter uses electronic circuits to cause the DC power flow to change directions, making it alternate like AC power. These oscillations are rough and tend to create a square waveform rather than a rounded one, so filters are required to smooth out the wave, allowing it to be used by more electronic devices.
