Honored Contributor --- Quote Start --- shift register based prbs can generate pseudo random noise. LUTs also can be used to store whatever type of noise you get from tools like matlab e.g. gaussian. You add noise signal to your signal sample by sample. sine wave can be generated from luts by hand or nco compiler. --- Quote End --- how LUTs can store signal ,and how to convert gaussan from matlab to vhdl,i đon't understand ??? how can generate sine wave by LUTs( i know nco blocks)
