Sir I am trying to use FFT 5.0 core in xilinx as follows for 50 hz Sin WAVE(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. 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 --------------------------------------- Posted through http://www.FPGARelated.com
