Tutorial: Causality

Learn how to determine whether or not a system is causal (with examples).

*CORRECTION*: Between 3:14 and 3:50 I mistakenly changed the system to move "n" inside the summation. The end result of each summation should be of the form y[n] = n0 x (... + x[n0-1] + x[n0] ). The final conclusion is still correct (system is causal). Thanks to piotrkakol1992 for catching this mistake.

There should be n0 instead of (n0-1) at 4:07 as n0 is not under the sum, but before it.
Just minor mistake, not that it changes anything.
Great videos!

Consider the system y[n] = T(x[n]) = x[n^2].
Investigate, showing all working to determine if
the system is (a) linear, (b) shift invariant, (c) stable, and (d) causal.

can i get someone to help me with this please
