FOURIER TRANSFORM OF SIGNUM USING MATLAB

Started by tough_guy_1977 October 8, 2004


i'm trying ot find the transform of signum(t) on matlab. I used this
code

syms t w
fourier(sign(t)) but i got an error saying sign does not take in values of type sym.
How else would I get to see the fourier transform displayed on
matlab screen if i don't use t as of type syms? I know that the
transform of sign(t) is 2/jw. But why can't matlab do that? Let me
know. Is there any way in matlab to find the symbolic transforms of
signum equations? Thanks
