    Use of properties in MATLAB

    Hi all, is there any document that explains in simple words how to use properties in matlab. For example a start function, **broken link removed** . How to use StarFcn and StopFcn ? Thanks,

    Sample live voice speech in MATLAB

    Hi all, I want to plot voice speech as long as a speech exist (attached code). I used an example from matlab on that matter, but I get in first 0.25 sec flat line as there is no voice (which is not true) at all times. But more important, the samples that I get displayed on the plot with delay...

    Frequency Modulation code

    the correct time domain should have been like this: t = 0:K*fs/fm -1 t = t*dt K is in order to increase the FFT input vector and by that increase its frequency resolution. K must power of 2. Df = Fs / (K*Ffs/fm)

    Frequency Modulation code

    Do you have other Bessel table that you can recommend (with much more accuracy), to verify that suggestion? I'll run a simulation and report. In other forum I was told that I need to adjust (it is too small for the given frequency) time vector according frequency of the information or to be...

    Frequency Modulation code

    hello albbg, thanks for your comment. When you looked at modulated spectrum, did number of harmonics was according Bessel "J" function? take this table as a reference: https://en.wikipedia.org/wiki/Frequency_modulation#Bessel_functions can you please simulate that code at matlab (if you have...

    Frequency Modulation code

    Hi all, I wrote a code for frequency modulation in matlab. I'm getting weird results at frequency domain, if you please look at the code and comment where i did wrong. By saying weird, i get wrong number of harmonics vs. beta. Also, for small values of Kp I don't get any modulation (maybe...
