Hi,
does anyone of you know a tool to do frequency domain plots ? Those axis with cute arrows labeled (omega)1, (omega)2 and so on ? I thought of something like x=A*cos(w1*t)+B*cos(w2*t) y=x^3 and that tool should plot me the resulting frequency components of y labeled with multiples of w1 and w2.
I know that Maple can do the algebraic calculations, but I've not seen a tool for doing this stuff and plotting the results ...
Regards,
Stefan
