Processor with Microcontroller, DSP and DAC functionality Hello All, I am trying to source a processor for an embedded application which has conventional microcontroller functionality, DSP functionality, and integral DAC and USB peripherals. In my searching to date I have not found anything suitable and I wondered if anyone out there may know of any suitable processors? ... 3 Jul 2008 12:30
Can you recommend a good explanation of the STFT? I've read Smith's "Scientist's and Engineer's Guide to DSP" and Lyons' "Understanding DSP," from reading these two books I have a grasp of the DFT. Now, I want to learn about the STFT. Can you recommend a book/website/article that presents a good, easily understandable explanation of the STFT? Preferably one th... 4 Jul 2008 01:50
Calculate variance of noise HI All I really need your help to understand this noise concept. Can you please tell me how to calculate noise variance for bandpass simulation? And does oversampling affects noise variance calculation. Your help will be greatly appreciated. Thanks Chintan ... 3 Jul 2008 15:36
How to test the variance of several correlated random variables Hi, I have a question about the verification of one of my analysis models. Simply put, there is a random process in which I have calculated the variance by the theoritical method. One condition is that I know the end result without the detail random variable correlation info (but I think the model has included t... 3 Jul 2008 16:37
How to convert continuous filter to a digital filter hello, everybody: I have one problem in do my master thesis, and need your help. The question is as follows: I have got the impulse response functions, the formulation of which is h(t) = u(t)exp(-(ln(t/tao)/sigma)^2), but i want to use a digital FIR filter with 7~8 taps or IIR filter with m zeros and n pol... 3 Jul 2008 08:23
Profiling on a SHARC21369 using Analog Devices' VisualDSP++ The documentation states that simulations use "linear profiling" while emulation requires "statistical profiling." I understand that, but isn't there a simple cycle counter that can be reset from VisualDSP++ that would allow a simple measure of total cycles consumed from point A to point B (via breakpoints)? -- ... 2 Jul 2008 10:51
Nature of measured 'digital' signals In practice, are almost all signals in DSP finally measured as a voltage? That is, even though the original may be sound pressure converted through a carbon microphone to variations in current, or may be charge on a CCD due to photons releasing electrons, in the end there is a conversion to voltage and from that... 2 Jul 2008 17:03
how to capture variables to PC realtime with jtag on C55x hi, guys in dsp group now, I'm working on C55x, and need to capture variable to PC realtime with Jtag for the purpose of debugging. For my system, there is no DSP/BIOS, so the RTDX can't work. I'm trying the Gel or Perl script to do this. Is it feasible? thanks for ur comments. my requirements: #1. no dsp/b... 3 Jul 2008 22:46
