Memory less system

A system is memoryless if for any $ t\in \mathbb{R} $ only on the input at $ t_0, $

 Eg:
 Y(t) = X(t) + X(t-1){ memoryless}
 Y(t) = X(t)+X(t-1)  { with memory}.<pre>\


'''Invertible systems'''

A system is invertible if distinct inputs yield distinct outputs.

Eg:
<pre> Y(t) = 2x(t) + 3
