Memoryless System

A system is classified as memoryless if at any given $ t_o\, $, the output $ y(t)\, $ at $ t_o\, $ depends only on the input at the time $ t_o\, $

Example

$ y(t) = 2x(t) + (t-1)^2 \, $

The system is memoryless because it only depends on the input $ x(t)\, $at current time. The $ t-1\, $ is just the value of the time when a signal is inputted into a system

Memory System

A system is classified as system with memory if the output $ y(t)\, $ at $ t_o\, $ depends on the input at the any time, whether it's in the future or in the past.

Example

$ y(t) = 2x(t-1) \, $

The system is a system with memory because it depends on the input $ x(t-1)\, $at time $ t = 1\, $.
