[guide]: the previous article about IIR design, or some friends click to read. Although I don’t know how the viewers feel, but I think there is always a favor to read, so I decided to continue this series. This article talks about the average filter, this topic at first glance is very easy. However, some […]

[guide]: in embedded system, it is often necessary to collect analog signals. It is inevitable to introduce interference into the signal chain of collecting analog signals. So how to filter out the interference? Today, let’s describe step by step how to design and deploy an IIR filter to your system. What is IIR filter? Infinite […]

[guide]: the previous article on the design of IIR / moving average filter. In this paper, we will talk about notch filter, which is very useful in mixing harmonic interference. The algorithm is simple and the implementation cost is low. This paper discusses its mechanism and application scenarios. Note: try to write a summary of […]

[guide]: the previous article introduces the moving average filter, IIR filter and comb filter. Today, we will talk about the design and implementation of FIR filter. In this paper, we still use 4w1h to describeWhat Why Where When HowSeveral dimensions are expanded. For easy understanding of 4w1h, the figure of 5W1H is still attached. What […]
