Sir I am trying to use FFT 5.0 core in xilinx as follows for 50 hz Sin WAVE(THROUGH ADC)for noise removal
- 64 Transform size
- Radix-2 burst mode
3.I/p data width 8 bit
4.Scaled
- Natural order(without cylix prefix) I want to know what is the value of scale_sch. Further I want to use inverse FFT for the O/P fft i.e XK_REAL AND XK_IMA. and display the same sine wave via DAC. So what is the procedure after FFT.
Should I remove all real and imaginary except fundamental frequency i.e calculated by xk_index.
and give this to FFT core(for inverse FFT) or anything else, kindly suggest me
bye Varun
