understanding the fft output in matlab xilinx system generator
hello everyone, i'm using a 256 fft core in matlab system generator, i have a bandpass signals from 750mhz to 1250mhz, im sampling at a rate of 1000mhz, for 750mhz im getting a 750mhz(single peak at 192 index value), for a 1000mhz im getting 0mhz, for 1110 im getting 110mhz, 1250 mhz i'm getting 250mhz, can anybody explain how pls??

i gt it , to sampling at 1250mhz to 1500mhz

sir, do u know how to implement a radix 2^2 algorithm of a 8 point fft, in matlab simulink, radix 4, and radix 2, are present in fft 9.0 core , but how to implement radix 2^2 algorithm of 8 point fft
