LFSR- white noise
Fibonacci LFSR to generare random number in order to generate white noise. Set of random number are pass through to FFT(power in db vs freq). However, the freq response is increasing at low freq. Then only maintain roughly flat for higher freq. Is there any problem with increasing at low freq?
the white noise spectrum is attached.
If yes may i know the reason?
FYI, i have seen lot of white noise freq response is almost flat from low to high freq.
Any other method to generate white noise?
Thanks
