Anyone using Linux?
inJust curious about how much Linux is being used for embedded DSP apps. If you're using it, what are your normal development tools?

Using the convolution of two rectangular signals to test a block convolver.

To test a convolver, a rectangular train of pulses can be convolved with ( a copy of ) itself to produce a triangular pulse. So suppose I have two quantities related to rectangular pulses: - Buffer size - number of pulses possible. The "10" in "float pulse1[10]" is the buffer size. Call this BufferSize. - The length of the rectangular pulse. This much be

Wikipedia has an informative page on Window functions. See this paragraph for context on dynamic range vs resolution: https://en.wikipedia.org/wiki/Window_function#Windowing The second part of that paragraph references tradeoffs between dynamic range and resolution. I'm assuming that the reference to 'dynamic range' means 'difference between center peak and nearby lobes', This woul...

Hi Group I'm sorry about posting all my formulas without any delay. I just wanted to get them out there while they are new, so that other people can use them if they want. Michael Plet
Stepper motors or servos?

I saw a real fast one armed robot. I was wondering if stepper motors was used or closed-loop control. I know NC machines use stepper motors but I heard the torque isn't as good as dc motors.

Hi Group Here is a method of time scaling that you may or may not have heard of. I have used it a few times and like it. Normally time scaling (change of duration without changing pitch) is done using STFT. That is overlapping DFT frames. In order to time scale, different amounts of overlap is used for analysis and synthesis. If a frame size of N, an analysis hop size of Ra and a sysnt...
Question about Gaussian window and parabolic interpolation

I have done some experiments with a Gaussian window applied to real signals. The signals were pure sinusoids of a fixed frequency and phase. I used this window: w(k) = e^( -(1/2) * (k - (N-1)/2)^2 / (a*(N-1)/2)^2 ) with N=32, k = 0, ..., N-1 and a = 0.265391249974779 I multiplied my signal with the window and did the DFT. Then I calculated the magnitudes around the peak. I took the...

I've recently seen in job listings, contract requirements etc. references to desiring engineers who are "experienced with Maker boards". What exactly is a Maker board? I gather it's not a brand name, but some general concept ... it sounds a little new-age or something. Is there a specific meaning? Steve
