Pulse random generator issue

Hello,

I'm new in Simulink and i trying to make a pulse random generatorpulse random generator. Pulses have amplitude (1 ) and width (6 nano sec). The signal has to be periodic. how can i do it? I apprecitate any help.

Thanks.

Hi @ibra01,

You can use this block to make a pulse random generator:

Set the sample time of the model to 6 nanosecond:

You can consider the below mentioned MATLAB function to be used in the pulse random generator:

function y = fcn(u)
    persistent counter
    if isempty(counter)
        counter = 0;
    end
    id = rand(1);
    if id > 0.5 && u == 0
        counter = 6;  
    end
    if counter > 0
        y = 1;
        counter = counter - 1;
    else
        y = 0;
    end
end

Hope this helps!
