We need to implement some white noise using preferrably analog circuitry. Is this easily achieved? We are going to use it in a sound generation device (audio-purposes), jam it through some filters, creating some hopefully interesting effects :-) I have seen some digital random generation algoritms, can these be used in some clever way with a D/A-R-2R ladder to produce noise? And if so, what kind of spectral distribution does this give? Tricky questions? I don't have a clue. I would be grateful for any pointers Thanx in advance / Mattias Engstršm (BTW, thanks for all the help I got on the RS232<->TTL level conversion) My direct email: maten149@student.liu.se -- ------------------------------------------- BassLab Production, Mix, Remix fascility Mail us : basslab@usa.net Call us : +46-(0)708-833331 -------------------------------------------
