3.A Joseph Mazzei - Time Invariant System
Good explanation of the property. The block diagram is very easy to read and understand. -- David Record
The explanation is very easy to follow. The large diagram helps to visually explain it very well. You may want to add something to the diagram to visually represent the definition (Y(t) = Z(t) therefore it is Time Invariant). Just a thought though. --Justin Kietzman
Good job with the block diagram. --Calab Tan
