Summary of Converting Acceleration Signals to Displacement Signals in Matlab

Summary of Converting Acceleration Signals to Displacement Signals in Matlab

Introduction: Recently, I have been working on data processing related to acceleration, needing to integrate acceleration into displacement. I found that there isn’t much information available online, so I will summarize what I have done recently! There are mainly two methods for integration: time-domain integration and frequency-domain integration. A common issue with integration is the … Read more

Fast Fourier Transform Algorithm for 51 Microcontrollers

Fast Fourier Transform Algorithm for 51 Microcontrollers

A faster version can be found in the C language implementation of FFT and IFFT source code, which does not depend on a specific platform. The porting is very simple, does not rely on other libraries, and allows customization of the number of points. The algorithm is derived from the usage instructions of the FFT … Read more
