FM Broadcast Stereo Pilot Detection Is there a digital technique for detection of the 19 kHz stereo pilot on commercial FM broadcasts? I'm looking for a way to extract the unmodulated pilot tone (only) from the analog RF carrier at low C/N ratios that would be below threshold with a conventional discriminator. Thanks. ... 7 May 2008 14:14
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

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 |
