Hi Guys,

I know that d/dx (sgn(t)) = 2*d(t)

But how can you use Fourier transforms and its' properties to get this answer?

If anyone can point me in the right direction it would be appreciated!

Thanks,

Simon

Convert d/dx (sgn(t)) into fourier, make the appropriate simplifications and convert it back to time domain by making the inverse fourier transform (it is easier by manipulate the fourier terms into partial fractions and then get tge inverse fourier transform easily).
