How do i find the impulse Response of the linear constant coef difference equation given in the photo? I got confused when recursion is included.

I have bad news...

Anyway just imput x[0] = 1, x[t>0] = 0 and y[t<0]=0 and see what happens for y[0], y[1], y[2]...

Ehm... Z transform?... You convert all in Z domain, then isolate for y/x and reconvert in time domain

Duderino i know i can give it impulse as the input. Should i find the close form expression using some samples of it, 0.1.2...? I was searching for a more elegant way of finding it.

Yeah its only a bunch of stupid delays thus i can do it without paper with z transform. But course have just started so we are Doing these things by fucking around mathematically in time domain.

there is no elegant way of finding it with what you have :)
