Hi Chukwuebuka,

As per my understanding, you want to re-create the waveform shown in the picture using simulink.

This can be achieved by using two "step" blocks. One block "Step" having "Step time" & "Final value" as 1 & 1 respectively and the second block "Step1" having "Step time" & "Final value" as 9 & -1 respectively.

Add these two blocks using an "Add" block. The resulting output is your required waveform.

Consider the block diragram shown below, for your reference:

You can refer to the documentation of "step" block, for more info:

Hope this answer helps you.

Thanks,

Bhanu Prakash.

Hi Chukwuebuka,

You can generate the required graph as shown by you in the attached image by using two step blocks and a switch block.

Configure the first step block to generate value 0, when x is in between 0 and 1. And after step time 1 units, give final value as 1. It will give output as follows:
