Automatic note stand1828 (8/1/2013 6:17:25 PM) comp.dsp
When musicians play music on notes, they have to turn the pages. Some
concert performers use human assistant for that.
Why couldn't they read notes from computer screen?
A computer could follow the musi... Vladimir
Simple nonlinear pseudorandom number generator220 (7/21/2013 10:10:38 PM) comp.dsp Let me suggest a minimalist generator of pseudorandom numbers. It is
based on the structure with nonlinear feedback. I haven't seen this

OT: Web design software1725 (6/27/2013 3:39:42 AM) comp.dsp
Could you advise software for website design. What is considered to be
good widely used tool for unsophisticated web design in our days?
Main requirement: software should be good by itself and easy to use.... Vladimir
Bandpass subsampling?333 (6/19/2013 3:53:44 PM) comp.dsp
There is a need to estimate power which falls into given wide (~30% of
Nyquist) bandwidth. Power spectrum doesn't matter; just overall number.
The power estimate is not needed often; so a decimation facto... Vladimir
AM3358 DSP benchmark124 (6/15/2013 4:19:26 AM) comp.dsp
There is necessity to port BlackFin VDSP code to TI AM3358. The later is
Cortex A8 core with NEON SIMD coprocessor (???).
BlackFin code uses DSP library; namely FFT functions provided with VDSP.
The BTD... Vladimir
VDSP is dead1449 (2/20/2013 4:33:17 PM) comp.dsp According to the information from ADI website, Visual DSP exists no longer.
Crosscore is official successor, albeit not quite compatible.
Does this imply near termination of BlackFin and Sharc product lines?... Vladimir
Non-text format for source code6240 (1/31/2013 7:20:31 PM) comp.arch.embedded For great many reasons, it would be convenient to have source code in some
rich format rather then plain ASC text. I could think of embedding
illustrations, links and data into file, custom coloring, indivi... Vladimir
Coherent MFSK1154 (11/28/2012 4:34:36 PM) comp.dsp There are communication systems with orthogonal multitone physical layer.
That is, one of N frequencies in the set is sent at a time. An example of
such system is "Olivia": http://en.wikipedia.org/wiki/Oliv... Vladimir
Video Controller :: Best Practices546 (11/19/2012 3:40:51 PM) comp.arch.embedded I have to design a video subsystem for instrument. Nothing really fancy;

Question about a Bandlimited Process173 (11/21/2013 2:21:31 PM) comp.dsp
Is it possible to even simulate a true bandlimited process? That is we
would like the spectrum to be zero at some frequency less that nyquist.
Surely passing gaussian noise through some FIR filter would ... westocl
sensor fusion77 (10/25/2013 4:29:32 PM) comp.dsp While Kalman seems to be the most used (optimal?) filter for sensor fusion,
its not nice for FPGA due to the required division. I was hoping LMS might
work, but it requires a desired signal which I don't have... jacobfenton
