Web1 Answer. Sorted by: 2. The principle here is that you can't get information from nothing. If a function throws away information, the inverse function would need to magically reproduce it. In this case, your function is throwing away the sign of the input value. Let's look at two examples. In the first, x [n] = 1 for all values of n: x [ n − ...
