Can two functions have the same frequency domain representation?

  1. Nov 10, 2011 #1

    I stumbled upon the following two functions which have the same freq domain representation,

    1.signum(t) = u(t) - u(-t)

    2. 2u(t)

    what is the reasoning behind them having the same f domain representation?
