how to find phase shift between two signals
Hi to all, I am presently facing problem with finding the phase shift in two Digital signals in MATLAB. I have two signals one is standard sine wave and other is output of my mechanical system which is again sine wave with some phase shift. can any body tell me how can I find exact phase shift in MATLAB. Thank ... 25 Aug 2006 09:02

DAC using PWM
Hi All, I am thinking of using PWM as a DAC. Unfortunately basic PWM (Lo-Hi at fixed point, Hi-Lo variable) always generates 2nd harmonic distortion and intermod distortion. I have 2 PWMs available. Would it help to drive one with the audio sample and the other with the ONES complement of the sample and the... 28 Sep 2006 22:01

32-Bit FFT
i am using ADSP-BF533 EZ-Lite I need a 32-Bit FFT for 24-Bit ADC written in ASM. A own FFT written in C is probably not fast enough. I've found only different 16-Bit FFT's in the Libs. Thx for Help. ... 19 Aug 2006 23:18

Rechargeable batteries
Hi all. I've just baught this digital camera that eats batteries. I need to get some recheargeable power source for this thing or I go either mad or bancrupt. Now, the camera can use either 2x AA batteries (these may be known ar LR6 in some parts of the world) or one CR-V3 unit. There are no problems gettin... 18 Aug 2006 10:09

Good ol' Fourier
Hi there, I don't have a background in DSP or a degree in Mathematics. I'm trying to implement an FFT. I understand what it does, but I don't need to understand how it works (yet). I've spent hours scouring the net and I've found either pages with complicated mathematical equations on, which are beyond me, or un... 16 Aug 2006 13:14

Blackfin 536/537 device driver under VDK
Anyone has the idea about how to create a new device driver? I create a tcp/ip lwip project and I would like to have a uart driver...how to do it? Except for the driver manager handler for tcp/ip phy driver, should I have another driver manager handler to handle the uart driver? ... 9 Aug 2006 12:39

Because the are in certain corridors but not others I assume them to be part of an INTERNAL communication system. Two quest... 10 Aug 2006 21:13

DSP56303 assembler tutorial?
Hello I need to learn assembly language for the DSP56303 (as fast as possible). Where can I find a good tutorial or a starting point? ... 9 Aug 2006 07:49

2D FFT:
Hello, I'm using a TI 5509A DSP that includes routines for a rfft and cfft. I need to perform a 2D FFT on an 64x128 word array of data. First I perform a 128-point rfft on real, sampled data across the columns of the array. I'm using the built-in scaling in the rfft algorithm which I believe scales the data by 2... 10 Aug 2006 00:54

Power Delay Profile
hi everybody, i'm trying to generate an etsi filter in order to simulate a channel. I did it but there is still one problem, i don't manage to take in account taps delays.. I read on the net we have to use the power delay profile of the filter but i'm not able to manage to coding of this method. I found a matlab s... 1 Aug 2006 14:09
