. 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.
