I am currently using Mathematica 3.0 for Engineering Circuit Analysis purposes. I am well aware of other existing packages designed for this kind of work. However, I have limited financial resource for affording those add-ons. Therefore, I will have to ask people how to get things done little by little as I go. Anyone who can help me with my questions would be deeply appreciated.
For the present, my question is ''How to describe to Mathematica a periodic waveform function f[t_] having a rectangular shape with different ON and OFF duration; a pulse function if you would like to call it?''
For the same matter, how to describe to Mathematica periodic waveform functions having triangular/sawtooth shapes.
Thank you for your expertise!
