Recursive Least Squares 4 5 (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? ... gyansorova

LMS #3 4 6 (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 Languages 25 13 (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. ... gyansorova

dsp eval kits 24 19 (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. ... gyansorova

FPGA General Purpose Computing 0 14 (2/13/2013 10:42:14 PM) comp.dsp They said it couldn't be done...but it appears that work has started on such a machine https://cug.org/5-publications/proceedings_attendee_lists/2006CD/S06_Proceedings/pages/Authors/Dellson/Dellson_Slides.pd... gyansorova

Root Locus 14 19 (1/15/2013 6:50:13 PM) comp.dsp Says in a paper I have found The root-locus method of Evans is one of the most popular and powerful tools for both analysis and design of single-input single-output (SISO) linear time-invariant (LTI) syste... HardySpicer

Discrete-time systems 43 32 (11/2/2012 9:14:49 AM) comp.dsp Suppose you convert an analogue system with no time-delay to digital. Say G(s) to G(z^-1) in backward shift format. Intuitively, should the discrete-time version always have at least a 1 step delay within it... gyansorova

ARMA models 4 46 (10/29/2012 4:04:22 AM) comp.dsp Suppose you have a system B/A and you estimate using an AR method g/A2 where g is a constant, the rest ie B,A,A2 = are polynomials in z^-1. Here I am assuming that you cannot get A directly = using an AR met... gyansorova

A daft question 14 31 (8/13/2012 8:03:57 AM) comp.dsp but my mind has gone blank! The output of an FIR filter is say s(k) = X'W(k) where X is the input vector and W(k) the weight vector. This is convolving the two vectors X and W to give a scalar s(k) ie the... gyansorova

Probability densities 5 48 (8/8/2012 8:09:46 PM) comp.dsp Suppose I add two noise signals y=x+v where x has a PDF Px and v has a PDF Pv What is the PDF of y?? I am led to believe that it is the convolution of the two PDF's of x and v - is this right and if so wh... gyansorova

DC to phase relationship with Low pass filtered sine and square wave multiplication 5 10 (4/5/2013 7:06:01 PM) comp.dsp Hello! From what I have read about lock-in amplifiers and signal modulation I understand that multiplying two sine waves, both with the same frequency, gives a two frequency component sine wave. One at DC ... Phat

The Story of Jesus and Mary in the Holy Quran 1 7 (4/5/2013 7:56:55 PM) comp.dsp The Story of Jesus and Mary in the Holy Quran The following three part series consists entirely of verses from the Holy Quran about Mary (Mother of Jesus) including her birth, childhood, personal qualities... bv4bv4bv4 (104)

Audio processing of more than one mic input 10 6 (4/9/2013 1:47:00 PM) comp.dsp What is a typical setup for processing multiple microphone signals? In the system I'm currently working with, the audio driver calls a callback= function which pushes the microphone audio to a queue and it... mjames2393 (69)

avgpower function in matlab 1 6 (4/9/2013 7:39:09 PM) comp.dsp Hi, I am using avgpower function on a PSD. I couldn't make sure what would be the units returned. It is in the orders of 10^-9. How can I convert this to uV^2? I know the output of PSD is in dB/Hz. And a... sedab

Estimating time offset between two audio signals. 22 5 (4/19/2013 2:46:18 AM) comp.dsp I'm looking for some recommendations on real-time algorithms which are able to estimate the time offset (delay) between two signals. One signal is the source signal (speaker signal). The other signal is a fi... mjames2393 (69)
