FFT and DDS IP core


Question

Hello,

I have a sin signal that is measured with accelerometer, after converting to digital value, it will transfer to FFT IP core for detecting the frequency. this frequency should enter to another block to generate sin and cos signal with unit amplitude. I think the DDS Ip core can receive the phase and generate the sinusoidal signal. is it right? but I have a frequency, how I can convert to phase?

Please let me know how can I configure FFT and DDS? is there any special configuration that I should attention on it.

in my opinion, I can't use the cordic, because the input signal of the cordic is phase (not frequency).

Thank you in advance for your time.

Fatemeh.

Hi @fatemeh,

I don't know what board you are using, though Digilent doesn't have a lot of advice regarding the two Xilinx IPs you mentioned despite this. There are some threads on our forum, link1, link2, link3, that may be helpful to you though.

Thanks,
