Introduction to Linear Time Invariant System Descriptions

spent like 15 minutes trying to decipher what a causal system was from my digital signal processing book. spent less than 2 minutes watching this explanation of causal systems and it made infinitely more sense, thank you!

I asked about time variant systems but nobody here on RUclips is explaining that topic .. What's the reason ?

Great! Thanks!

If anybody have concepts about time variant ( non autonomous ) systems then share with me ..
