Ok I'm fucking losing it over this so I need some help.
I'm doing my bachelor's degree in France and I'm struggling with Z transform, not the concept, just the exercice (see pic related).
We have a Z-equation Y(z) = X(z) + 0.5*X(z-1) + 0.25*X(z-2)
And they ask us to find the transfer function of the system.
I don't fucking get how we can do that using this

Signals and systems thread I guess
