Newbie to DSP - Phase shift detection Hello everyone. I'm completely new to DSP, coming from a background of PIC18. I have two mics that I want to use for sound direction detection, and I guess using fourier transforms to get the freqs out from one channel then looking for a rough match in the second channel over time (and vice-versa) is the co... 7 May 2008 13:24
What's the use of a 192 kHz sample rate? Manolis C. Tsakiris wrote: ... in DVDs the audio signals are modulated digital pulses (and not analog waveforms), such as PCM, and their spectrum is no longer that of an acoustical signal (20Hz-20kHz), justifying the need for a higher sampling rate. That sounds like doubletalk to me. Would you pl... 7 May 2008 14:14
Is 44.1 KHz sample-rate enough to cover the entire human hearingrange? Green Xenon [Radium] wrote: SteveSmith wrote: One of the common arguments used to justify these higher sampling rates is nonlinear effects, both in the ear/brain and loudspeaker systems. Here's one version: http://www.digitalaudio.dk/technical_papers/aid.pdf Keep in mind that audio manu... 6 May 2008 23:25

DSP Architect Hello All, I am still searching for the ever elusive DSP Architect aka Big Foot. I have a fantastic opportunty for a DSP Engineer with expierence in processing algorithms for the physical layer of high speed optical data communication networks. If you are or know of or even heard of someone with this skill set t... 24 Apr 2008 15:03
Anyone in India interested in selling 2nd hand DSP boards? Hello All, In India it takes 7 weeks to procure new DSP boards as the retailers do not stock them and it comes via Singapore channel. Add to it overhead of 75%, in form of duty and retailer margin. I am looking for Blackfin BF561 and TMDSEVM642 for purchasing. If anyone in India... 24 Apr 2008 14:15
Is octave good to do image processing? Hello All, I found octave to be good for signal processing applications. But is octave good for doing image processing too? The reason why I am asking this, is sometimes back I was using scilab for image processing applications. when I ventured more in depth I found it to be dead sl... 24 Apr 2008 14:15 |
