Coursera 1 4 (4/27/2013 9:08:14 AM) comp.dsp I have previously posted about some Coursera courses though with less interest than I might have expected. Maybe this one people will find more interesting: https://www.coursera.org/course/digital -- ... glen

1250MHz ADC 5 9 (3/29/2013 5:59:17 AM) comp.dsp 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. Much filtering and echo cancellation is done to th... glen

Learning from Data 1 18 (3/27/2013 9:13:24 PM) comp.dsp I previously posted here about the Caltech Machine learning course, "Learning from Data." I just learned that the last session ever will start next week. Registration (free) is at: https://telecourse.... glen

Machine Learning Course (free) 6 32 (12/8/2012 12:15:52 AM) comp.dsp This might be a litte bit away from DSP, but maybe not so far away. A new session will start in January: http://work.caltech.edu/telecourse.html In case some here would be interested, and hadn't heard ... glen

Numerical or Analytical 9 60 (6/15/2012 11:05:39 PM) comp.dsp I hope this isn't too far off topic. I was wondering recently about the changes in how math is taught, with more numerical emphasis than there used to be. For those who haven't taken an SAT recently, not... glen

Lytro 2 80 (3/15/2012 2:11:19 AM) comp.dsp After seeing discussino of the Lytro light-field camera, the first thought I had was that DSP would be pretty important in making it work. Yet I don't remember seeing any discussion of it. The article describi... glen

unclipping 14 66 (3/5/2012 1:12:03 AM) comp.dsp I have a digitized WAV file about 71 minutes long (actually, 10 files totaling 71 minutes) with three samples clipped, I believe not all consecutive. I can't actually hear them, as I usually can with much mor... glen

The or operator and the preprocessor? 3 75 (2/13/2012 2:08:00 AM) comp.lang.c++ error: "or" cannot be used as a macro name as it is an operator in C++ In C, the preprocessor does what its name says, and occurs before the compiler sees tokens and reserved words. Is that not true in C++? ... glen

JBIG2 AT pixels 0 71 (2/8/2012 5:58:10 AM) comp.text.pdf I am working on a JBIG2 encoder, and am considering moving the AT pixels to other positions. I wonder if PDF readers special case the default positions, such that they would run faster for that case. So far, ... glen

integer multiplication #2 1 0 (5/20/2013 3:46:11 AM) comp.lang.c (cross posted to comp.dsp and comp.lang.c.) are compilers now-a-days smart enough to multiply two N-bit numbers to a 2N-bit result without wasting instructions in the generated machine code? like, we ... rbj (3911)

Gravity Vector Tracking 38 5 (5/1/2013 7:54:06 PM) comp.dsp Looking for suggestions or pointers on how to track the gravity vector in 6D data. -- Randy Yates Digital Signal Labs http://www.digitalsignallabs.com ... yates9428 (362)

struct padding is slower than struct packing 19 4 (5/2/2013 11:17:02 PM) comp.lang.c Hi all, As far as I understand, struct padding is implemented in order to speed up = the execution of a program. I did this small example below in order to veri= fy this issue. However, surprisingly, my pr... diegotorquemada1 (81)

Embarcadero C/C++ Compiler available 24 5 (5/3/2013 4:40:35 PM) comp.lang.c Hi: If you would like to test/try out the new 'Borland' C/C++ Compiler (from Embarcadero) BCC 6.6.0, there is a link below. This console-only compiler was extracted from the C++ Builder package... med_cutout_syntel (718)

Standalone C wrapper to C++ library 9 8 (5/7/2013 10:51:45 PM) comp.lang.c Hi all, I am not an experienced C developer and would like to know if there are good resources for, or better yet real-world examples of, wrapping a C++ library in C such that application written using it don'... aditya.siram (54)

Clipped before FFT 28 2 (5/10/2013 11:17:08 PM) comp.dsp I have been experimenting with some time-domain pre-processing to improve the reliability of an FFT application. The application is extracting the RPM of an engine from the sound it makes. Prior to these e... no-one5677 (19)

reference type for C 55 1 (5/16/2013 2:08:43 PM) comp.lang.c I like the reference type that has been introduced with C++ I wondered why isn't that feature retrofitted in C. Is there something hindering it? thx - roar - ... roland.arthaud (4)

A purely theoretical question 17 2 (5/16/2013 4:59:48 PM) comp.dsp Hi group I have a purely theoretical question. When doing a FFT of an unwindowed pure sine signal, if the frequency doesn't match a bin frequency, many bins will have a magnitude > 0. Because the magnit... me6228 (314)
