Generating multi-bit pseudo random sequence
Hi, Say I use a 16-bit LFSR set up to generate a maximum length pseudo-random sequence. According to property (3) here: 'The modulo-2 sum of an m-sequence and another phase of the same sequence yields yet a third phase of the sequence'. Does this mean that I can generate say 4 different phase of the sequence, co... 10 May 2010 19:52

continuous radian frequency vs digital radian frequency
hello Forum, I know that a continous time sinusoids can have any radian frequency w=2pi/T, therefore any period T. A discrete time sinusoids has a radian frequency equal to 2pi/N (where N is the number of samples). No matter what N is, a discre-time sinusoid, if periodic, will always be periodic with period=2pi i... 8 May 2010 22:09
Resampling/interpolation (uniform and non-uniform case)
Hi all. I'm doing some work on a commercial black box system with three sensors that are being sampled at 10 Hz. One of the sensors are running freely, while the two other sensors are polled by a linux computer. For one of the polled sensors there is a unpredictable delay from when I request data to it is be... 10 May 2010 03:21
Practical Bit-loading (ADSL/VDSL): fundamental problem
Hi, I have a fundamental doubt regarding bit-loading. I was trying to simulate VDSL2 system in matlab. (Issue is also applicable to ADSL2+ standard..... might be applicable to others). Fact#1) Bit-loading algorithms assume that the "energy of subcarrier" increases monotonically with information (i.e. as n... 9 May 2010 15:24
Overlap-add induces ring-modulation
Hi, I have implemented overlap-add method for granular pitchshifting and eventually I realized, that since the "overlapping" is basically multiplying with a hann window or something, it basically is a ring-modulation. I unfortunately verified this on a spectrum analyzer - it added f+m and f-m to the testing frequenc... 7 May 2010 18:56
On Quaternions -- Book Recommendations?
One day a few years ago, while browsing through Powell's Technical Books (a brain candy store for engineers), I ran across "On Quaternions and Octonions: their geometry, arithmetic, and symmetry". I bought it, thinking that it'd be a good how-to book on quaternion math. When I got it home and read it, I reali... 26 May 2010 12:26
Tool to practice DSP algorithms
Hello, I'm an undergrad student and want to learn how to implement DSP algorithms on embedded systems. The first step, I think should be to learn how to implement them in C or C++, but I have two questions before I begin. Q1) Should I start with C or C++? which is used more and why? Q2) Recently there is a ... 13 May 2010 10:27
