曾经听过哈工大深圳研究生院李教授的讲座，李教授说，控制系统的实质，就是滤波器的设计。尤其在电机控制系统设计中，滤波器是必不可少的存在，很少观测器实质也就是滤波器，比如拓展反电势模型等。 在无传感器控制方案中，滤波器相对用得不多，比如 ...

【导读】：在嵌入式系统中经常需要采集模拟信号，采集模拟信号的信号链中难免引入干扰，那么如何滤除干扰呢？今天就来个一步一步描述如何设计部署一个IIR滤波器到你的系统。写这篇文章考虑到很多粉丝是做单片机系统开发的，经常会需要采集模拟信号 ...

Infinite impulse response (IIR) filter implementations can have different forms (direct, standard, ladder, …), different math (fixed-point or floating-point), and different quantization (number of ...

In many applications, you need to apply a post-processing digital filter on your data. A common example is the filtering of data from an ADC. This application note shows an IIR filter that can be ...

A range of 5th to 11th order digital IIR filters for conditioning and optionally decimating data from an external source and to DMA the output into pr ...
