Pulse Density Demodulation
Hello. I have a few problems using Matlab low pass filters to demodulate a pulse density modulated signal. My Matlab code generates a series of photon arrival times distributed by Poisson statistics and dependant on a time varying input. This gives me an output array that represents the time instance of photon arr... 28 Apr 2010 11:42

Masked block, Simulink - force initialization commands on resize
Hi all, I am trying to create a 'smart' mask for my Simulink block - I need a functionality similar to the Constant block: Display the value of a parameter if it fits inside the block, otherwise display some text (if the number is too long). Based on the actual width of the block I can prepare the string to be displa... 30 Apr 2010 08:22
