Design of IIR filter for hand-held teaching series

[guide reading]: it is often necessary to collect analog signals in embedded systems. It is inevitable to introduce interference into the signal chain of collecting analog signals, so how to filter the interference? Let's take a step-by-step description of how to design and deploy an IIR filter to your system. What is an IIR filter? IIR (Infini ...

Fast Fourier transform (FFT) source program

The source program I wrote is based on MATLAB platform, but its idea is based on C + +, because MATLAB has its own fast Fourier transform (fft) function. I didn't understand the operation principle of fft in MATLAB, so I wrote a source program. The theoretical knowledge of FFT can refer to the contents of these bloggers< ht ...
