I am currently working on an experiment to connect DSP to AD5390. DSP controls AD5390 through SPI bus. Currently, writing DSP program is not a problem, but I am still having a headache on how to write...
This is my first time to do Fourier. Now I want to collect 125HZ and 225HZ signals. So what should my sampling frequency and sampling points be? Can you help me calculate it? It would be best if you c...
