I liked how you gave specific examples with your proofs. It helps the reader understand what's going on. Your explanations for memoryless systems and systems with memory was clear. -Phil Cannon
Your examples are correct and make the definition more clearer. Actually I chose memoryless or with memory,too. But I've got a question. whether y(t)=1(or any constant)is memoryless or not? - Hetong Li
The definition you showed was very clear and the examples really emphasized well what you were saying. -Eric Smith
What a piece of art, i like the way you explained why one of them was memoryless even though there was some time t outside. -Jonathan Morales
THE EXAMPLES given for systems with memory is WRONG. (t-3)^2 is a scalar.So system is memory-less.
