Hi ,

I am trying to simulate a therapeutic medical device that operates from 2700 V to 3000 V in 900s. I want to simulate the increase in voltage as follows : 2700 V , 0-88 seconds ; 2800 V , 88-176 seconds ; 2900 V 176 - 264 seconds; 3000 V 264 - 900 seconds. Can I use a step function to increase the volatge as mentioned above ? Will a single step function do ?

I suggest that you use a piecewise function.
