Power Spectrum and Frequency Bands [3 Articles]
Posted by sedab in Comp.DSP on Apr 3 2013
Hi,
I have a power spectrum and I want to get the frequency bands. Should I use
a band-pass filter first to get the bands, or can I simply divide the PSD
data at needed freque... 
SDR - Demodulation of DVB-C [12 Articles]
Posted by Vieriksson in Comp.DSP on Apr 2 2013
Hi,
I am having some issues with the IQ-demodulation of a DVB-C signal. Even
though it works fine on synthesized data, I can't get the timing recovery
to work on real data. Can ... SRF-PLL problem [20 Articles]
Posted by Mimar in Comp.DSP on Apr 2 2013
Hello,
can somebody give me an advice? I have decided to use SRF-PLL system for
frequency tracking/estimation in 3 phase power grid recently but there is
some problems:

Posted by Tim Wescott in Comp.DSP on Apr 1 2013
Are there convolutional codes that guarantee an encoded signal with equal
numbers of zeros and ones? Are they useful?
I'm thinking of a convolutional equivalent to the 8b10b ... OT Can a GSM phone witout a SIM card dial 911? [2 Articles]
Posted by MarkK in Comp.DSP on Apr 1 2013
A bit OT for here but there is so much mis-information on the internet. I
think this would be a good place to get the facts.

... Estimation of delay between speaker signal and microphone signal (AEC) [33 Articles]
Posted by Mauritz Jameson in Comp.DSP on Mar 29 2013
I need to estimate the delay between a loudspeaker signal and a microphone signal in real-time. The delay might be as large as 400ms.
If I buffer up both time domain signals in ... 1250MHz ADC [6 Articles]
Posted by glen herrmannsfeldt in Comp.DSP on Mar 29 2013
While following the discussion about 8b10b coding, I happened to see a
page on 10GbaseT. It seems that 1250MHz 7 bit ADCs (and 10 bit DACs)
are required.

Posted by tom00 in Comp.DSP on Mar 29 2013
Hello all!
I have to implement a Schmitt trigger in software on a DSP. I was thinking
a while about a good implantation, but I just came to the simple solution
with has nested i... Sample aplication [7 Articles]
Posted by Mac Decman in Comp.DSP on Mar 28 2013
A while ago I posted a sample application for impulse response
analysis on soundforums.net. There are some pretty strict
requirements for the stimulus, but otherwise, it is just...
