LMS Question 1 30 (10/26/2008 7:37:34 PM) comp.dsp I have read books on this (Haykin) but still none the wiser. What exactly in physical terms is the difference between Convergence in the Mean vs Mean-Square? Yes I know the formulae well but what would be the p... sheepshaggerx

Van Trees Books 3 24 (8/24/2006 9:08:39 PM) comp.dsp I remember in the 70s a collectof of about 4 books by Van Trees on Detection Estimation or some such. Is this 2002 book http://www.amazon.com/gp/product/0471093904/sr=1-2/qid=1156376768/ref=pd_bbs_2/104-039409... sheepshaggerx

Time Stamp Question 0 27 (8/16/2006 9:36:29 PM) comp.lang.labview There are a lot of example progs which use the time stamp format in soem way. One of them has a little .vi which appears to update the time in some way and it is bundled along with 1/sampling freq (dt) + the ac... sheepshaggerx

FM or PM? 1 29 (7/25/2006 11:21:04 PM) comp.dsp Take a normal analogue FM radio system (like the ones in a car). Now FM is defined as cos(Wct + k integral( f (t) dt ) ) and PM as cos(Wct + kf(t) ) Where f(t) is the signal. where k is a constant dependi... sheepshaggerx

Labview Application Builderv Question 1 32 (7/20/2006 9:07:15 PM) comp.lang.labview In version 6 Builder was an add-on but in V7 it came as part of V7. Now in 7.1 and 8 it appears to be an add-on again - any comments? Thanks ... sheepshaggerx

Cross correlation and system ID 2 27 (6/22/2006 9:52:36 PM) comp.dsp I was looking at this link http://www.prosig.com/signal-processing/CorrelationExample.html and is says that for a system with excitation x and output y that the transfer function is found to be H(f)=Gxy(f)/... sheepshaggerx

GPS Question 2 42 (6/28/2005 10:23:09 PM) comp.dsp I am looking for the maths that show me how to work out the intersection of three Hyberboloids.)(as used in GPS) I can only find sketchy references to it and nothing concrete. Thanks ... sheepshaggerx

I-Q vs PLLs 15 30 (6/8/2005 2:13:40 AM) comp.dsp Which gives best performance, a Phase-locked-loop (say all digital - software) or I-Q (ie using arctan and then differentiating) demodulation.Reason I am asking is that a PLL is supposed to be the best - is it ... sheepshaggerx

Undersampling Question 27 32 (6/7/2005 10:09:14 PM) comp.dsp Dear folks, I was wondering if you could help me with this problem. I have an accelerometer with a resonance of say 15kHz. I need to do envelope detection of this (acts a bit like AM with 15kHz as the 'carrier... sheepshaggerx

Question about Autoregressive model? 2 31 (8/14/2006 11:40:14 PM) comp.dsp Hi, I am reading some websites about Autoregressive model. I have some questions which I would like to ask you all: 1. To use the AR to predict Yn, do I need always to assume the Yn is a stationary process? Wha... VijaKhara (97)

Nyquist Didn't Say That 188 110 (8/22/2006 10:23:14 PM) comp.dsp Kinda off topic -- A month or two ago there was a spate of postings on these groups displaying a profound misunderstanding of how to apply Nyquist's theorem to problems of setting sampling or designing anti-... tim177 (4406)

Post-doc in Acoustic Event Detection (US citizens only) 65 29 (8/24/2006 8:44:55 PM) comp.dsp The International Computer Science Institute (ICSI) invites applications for a postdoctoral Fellow position in acoustic event detection. The Fellow will be working with Nelson Morgan, along with international c... dave_gelbart (15)

Question about fourier transform and laplace transform 5 41 (2/1/2008 1:07:47 PM) comp.dsp Hi I am a computer engineering student.I have to know the difference betwee Fourier transform and Laplace transform. Because we have studied laplac transform previous semester, that time to find a frequency res... nadunalexander (1)

Circuit with two poles? 4 29 (2/2/2008 1:45:23 AM) comp.dsp I am looking for a circuit whose transfer function (V(z)/I(z)) comprise just two poles. Is it possible to build such a circuit using just RL elements? Thanks for your help Gokul ... swamygok (13)

A question on phase and timing recovery 3 21 (2/2/2008 3:37:38 AM) comp.dsp Dear all, I have a question on carrier recovery (CR) and timing recovery (TR). My homework is to compensate phase and timing jitter of a data stream. This stream also contains some known data (training symbol... kbasod (3)

Future of DSP? 20 23 (2/7/2008 4:08:20 PM) comp.dsp For sometime I have been wondering what will be the future of DSP maybe 5 years down the line or 10 years down the line. Based on that future of many people related to dsp "dsprelated people" will also take sh... bharat310 (237)
