Sir I am trying to use FFT 5.0 core in xilinx10.1 as follows for 50 hz SinWAVE(THROUGH ADC)for noise removal 1. 64 Transform size 2. Radix-2 burst mode 3.I/p data width 8 bit 4.Scaled 5. Natural order(without cylix prefix) I want to know what is the value of scale_sch for FFT and IFFT for getting O/P width same as I/P width i.e 8 bit in my problem. As I want to use same IP core for FFT and IFFT.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
This doesn't make sense. There is no need to make an FFT over all freqs if you just want to keep one of them. Do an IQ-Modulation-Demodulation with a sharp small band filter in between.
