Why do we decompose signals to even and odd
  1. What is the difference between even and odd signal?
  2. Is unit step function even or odd?

What is the difference between even and odd signal?

Even signals are symmetric around vertical axis, and Odd signals are symmetric about origin.

Is unit step function even or odd?

For example unit step function , it is neither even nor odd as it doesn't have any symmetry.
