Hi Gentle comp.dsp Denizens, The September issue of the JAES has an interesting article on noise power modulation in delta sigma modulators by Lokken et al. I was wondering if folks agree with his conclusions in section 1.2, where he states essentially that a 1-bit delta sigma modulator will have noise power modulation whether dither is used or not. One thing find odd is that in section 1.1 he uses RPDF rather than TPDF dither for the dither noise component v. I haven't read the article carefully yet, but I thought I'd try to get some discussion going on this really interesting and cool topic. -- % Randy Yates % "My Shangri-la has gone away, fading like %% Fuquay-Varina, NC % the Beatles on 'Hey Jude'" %%% 919-577-9882 % %%%% <yates@ieee.org> % 'Shangri-La', *A New World Record*, ELO http://home.earthlink.net/~yatescr
