Hello, I need to plot exact the same graph as the output coming from a Schmitt Trigger by using only Simulink. No scopes shall be used since it has negative values on X axis, it should be demonstrated by a Simulink XY Graph block by creating appropriate inputs both for X and Y axes (there are no limitations on which signals/blocks you are using while you are creating those inputs, you can use everything inside Simulink but no Matlab script files etc.). I tried many signals, trigonometric blocks and so on but I couldn't obtain the result. The graph should look like this:
I hope someone can help me, at least a clue will be much appreciated!
