Impulse Train

Another weeke another problem I need help with solving in Mathcad.

I have beed tiying to gt mathcad to sketch an impuls train, But I can't after the troubles i had with vectors im not suer if there is an easy way to do it but I would like to hear, if you have a way of doing it other than transforming the impulses to vectores and then plotting the vector in.

There are more details in the worksheet

Regards

Will something like the attached do?

I didn't even think to look there... but yes I think i will do nicly.

The only draw back is that it also shows the top of an triangle where f(t)=0 but it not a big problem since it is technicaly correct

SO thank you and if you have a tip on how to remove the trianles on f(t)=0 pleas tell

Define a range variable t:1;2 before the plot, and set the lower limit for the y-axis to 0.

Yeah I can see how i can do that, I was hoping for another way. I mean the lees i have to define outside the graph the better.. or that is what i think anyway.

You could choose Symbol Weight as 'p'. The arrow heads would still be there, but much smaller - barely visible when f(t) = 0.

Or set the minimum y value to something like 10^-8 (zero doesn't quite do it).

Still a bit unclear what you want, exactly. But, you can certainly turn off the symbols on the plot and just get:
