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


Could use an example, but other than that the block diagram is pretty cool. - Eric Zarowny

The block diagram is an excellent way to represent systems. I would give you an A+ if I were the professor :-) The whole procedure to determine if a system is time invariant or not is well understood from your definition-- Monil Goklani

Very good description of the process, and its application. The outputs and inputs are shown clearly, and although no examples are given, this is a very practicable and workable definition --Tyler Houlihan


Good explanation, I like the block diagram. It is easy to follow and provides an easy, accurate explanation. -- Ben Moeller


The block diagram makes this definition work perfectly, great job. -- Nick Block
