I am currently working the figure through below.
as it is an FIR Filter i have worked out using convolution that the output is 4,2,4,6,0,0.
i am trying to obtain the 'z' domain transfer function of the filter below using h(n)
using the $h(n)$ 2,-1,3
I have started to obtain the $z$ domain transfer function with
$y(n)=2x(n)-1x(n-1)+3x(n-2)$
any help?
