Hello everyone.
We are working on a system that communicates a cRIO device with a PC. We acquire a signal and apply the FFT to reduce the number of data sent, via FIFO - DMA, to the PC. we have tried to eliminate the continuous component of the wave that we acquired so that the harmonic of 0 Hz does not appear when performing the FFT.
We have tried to eliminate the mean of the acquired wave to obtain only the AC frequency however the FPGA only works with FXP so we are not able to however we can not do it since the FPGA only works with Fixed Point.
Does anyone knows how can we do it?
I have attached the block diagrama both for FPGA and PC and the project.
Thanks in advance.
EDIT: I do not know how but I have post this twice. If someone can close or delete one of the post please do it 🙂
