Hello, LFSR (linear feedback shift register) generate flat spectrum and I prosssed the output of LFSR for DFT to see flat spectrum and it does generate. Somebody suggests mathamatical model to prove LFSR generate flat spectrum. I would ap

Hi guys, It is a known fact that LFSR generate flat spectrum, I choosed LFSR to test my 3rd order polyphase comb decimation filter with decimation factor of 256. I am wondering what would be the lenght of LFSR ? it should be 4 bit or 8 bit or 10 bit ?? All generate flat spectrum. What c

Hi, How to implement the LFSR of 18bit sequence long with 7bit output in Matlabe simulink? I have rough idea of using pn sequence generator and have already read the help. The purpose of using this is to lower the spur level before phase bits truncation. Please guide me how to use pn sequence generator.
