three_signal_delay.mdl

I need to create three signal of a time period . Such as D1= 0.5, D2=D3= 0.25. (D1+D2+D3=1)

I tried using transport delay and Discrete Variable Time Delay but not getting required output. As you can see in given simulation the D3 has a offset in its value. Can't I just have it as one signal at a time.

hi Muhammad,

Your D1 does not contain any delay and your initial set contant values for D1, D2, D3 (.6, .2, .2) differ from your set values D1= 0.5, D2=D3= 0.25. (D1+D2+D3=1).

Why don't you use just a Delay block?

Good luck.
