demux

Hi every body, I have 2 impulses. The second impulse comes after the first one 30ns. I multiplexed 2 impulse to 1 line at the modulation side. Now, I don't know how to seperate and get each impulse drive to each demodulater using simulink blocks. Please help me. Thank you very much.

If your multiplex operation is using the SUM block, you will have a hard time separating the impulses. It may be possible to detect the first impulse, then trigger processing of the second impulse a fixed time later. Stateflow has temporal operators that can be used to express such an algorithm.

If you used the MUX block in Simulink, you can use the DEMUX to get the elements of the vector.

Dear Mr Seth Popinchalk,

As you written:"...using the SUM block, you will have a hard time separating the impulses". But the Sum block performs addition or subtraction on its inputs so how can I use SUM block to separate impulses? Can you explan about that.

Thanks for your enthusiasm.
