Custom square wave in simulink

I need to create a square wave with two different amplitudes as shown in the attached image. The total time duration is 50s. The signal can be divided into two parts: i)Upto 15s, I need a step signal of amplitude -1.5. ii)Starting from 15s onwards, I need a square wave with lower half of -2, and upper half of -1 (With apmlitude of 1, Period of 20, pulse width of 50%). I am able to simulate the part ii) in SImulink using the pulse generator. However, I need a signal with both part i) and ii), and that I am unable to do using only pulse generator or other ways. The file fig contains the waveform of part ii) Please help.

Hi

You need to use "Signal Editor" block to create custom signals to achieve the desired result. I have created the same signal with the help of "Signal Editor". Refer to the below scope image:

For more information on "Signal Editor" Block, refer the following MATLAB documentation:
