    You can get OpenOffice for free.

    If you want to play with waveforms and see how they combine, then you can generate your waveforms in the spreadsheet and plot the results. Very simple and easy (for basic stuff where you are just working with the signals).

    Have you ever used Excel?

    Look at this. Is up to you understand what I did. Most probably not scientific but in the basics, it works.

    It took maybe three minutes to write it and get the graph.

    Delete the ".txt" extension so it will beahve as an Excel file.

    Good luck.
