Posted by alb in Comp.DSP on Oct 31 2014
Hi everyone, I have an encoder which is delivering 22bit data for a 360 rotation. The rotation is accomplished in ~800ms but the serial link from the encoder is running such... decimation and resolution

Posted by cmbeck_2008 in Comp.DSP on Oct 31 2014
In order to reduce the micro requirement I would prefer to first calculate the magnitude from 3 x accelerometer signals then do the filtering. Is there any good reason not to other... magnitude first then filter

Posted by Cranisch in Comp.DSP on Oct 31 2014
Hello everyone, I have a maybe quite easy question but I got stuck there. So hopefully you can help solving it for me. From a measured power signal (I am not able to have th... Newbee question: FFT to total signal power

Minimal DSP for video transcoding

Posted by Xata in Comp.DSP on Oct 30 2014
Hello. I am new to DSP, even more - i am not even in DSP theme at the moment. Problem is - i need to transcode video from 12mbps MPEG2 to any other format, that will need less bps... Minimal DSP for video transcoding

Gibbs   [16 Articles]

Posted by in Comp.DSP on Oct 30 2014
So you model a square wave by the sum of sine waves. Suppose you take 5 or 6 and get the classic Gibbs phenomena. Now suppose that you know exactly where the 5th or 6th harmonic is... Gibbs

Posted by Max in Comp.DSP on Oct 24 2014
I noticed a post about 'pre-ring' here recently (couldn't find the thread again), and I'm trying to follow up to figure the implications to audio systems. Web searches turn up co... Linear phase vs Min. Phase
