Analysis of Discrete time LTI system using Z-Transform(Causality & Stability) 

I literally have my final exam after 35 min and I just understood the concept, thank youuuuuuuuuuuuu saved my life

you have explained this topic very easily . thanks

why first ROC (i) |z| > 3/4 and why second one is (ii) |z| < 1/4 ?

thank u very much

Mam how to take lesser than or greater than for the poles pls tell mam 🙏

Thank u

Tq mam

And here one conditions she has forgot : When 0.75 < | Z | < 0.25 Then system will be Anti - Causal but Stable system ❤🎉
