Scrambling of voice26 (10/26/2013 5:34:19 AM) comp.dsp With all this talk of snooping by government on the individual, is it a goo=
d time to have a scrambler? I realise that they could crack them too but wi=
th an extra layer on top...In other words scramble the... gyansorova
Causality249 (10/8/2013 5:52:15 PM) comp.dsp Somebody told me that a differentiator is classified as an uncausal system =
because it has more zeros than poles. This would mean that it needs informa=
tion from the future to effect the present which is no... gyansorova
Active noise-cancelling2811 (9/8/2013 6:02:30 AM) comp.dsp For active noise-cancellation to work, what distance does the speaker produ=
cing the so-called anti-noise have to be away? in headphones they appear to=
have everything all encapsulated but I thought you ne... gyansorova
Sampling1028 (6/24/2013 8:47:58 PM) comp.dsp Somebody just told me something I cannot accept. That the usual sampling th=
eorem doesn't work too well when there are fast moving transients in a sign=
al. To me this means that you are just not sampling fa... gyansorova
Ensemble Kalman Filter525 (6/11/2013 9:25:34 PM) comp.dsp Came across this recently but didn't understand in plain language why it was needed. Does anybody know? Why is a Kalman filter not do the job?
Recusive Least Sqeares (RLS)041 (6/3/2013 11:15:02 PM) comp.dsp A little while back I posted a question asking if anybody knew who invented=
RLS. Most people said Kalman. I recently found out in a paper that it was =
Guass!! Although this lay unused or undiscovered until... gyansorova
Recursive Least Squares442 (4/29/2013 9:33:43 PM) comp.dsp We all know that Guass probably invented block least-squares, but who invented Recursive Least Squares?
LMS #3437 (4/23/2013 7:37:57 PM) comp.dsp In Haykins book from 20 odd years ago he mentions some very good points about convergence. Namely that if the correlation matrix from the driving noise has eigenvalues that are widely dispersed (say 100:1 ratio... gyansorova
Programming Languages2546 (3/11/2013 4:01:59 PM) comp.dsp Should we be using Matlab,Labview and fancy graphic tools to help us rapid prototype designs or should we all program in assembler cos it's tough and less people can do it.
dsp eval kits2450 (3/7/2013 7:42:11 AM) comp.dsp can you recommend on that has adc and dac floating point processing. Doesn't need to be too powerful. suit basic motor control. eg only needs to implment basic integrators/lag lead compensators.
