Hello,(adsbygoogle = window.adsbygoogle || []).push({});

am having an understanding problem, about an exercice on LTI systems with unit sample response.

i've been given the graphical depicted output y[n], and the following output x[n]= u[n]-u[n-2]

the system is as follow

x[n]----> h_{1}[n]----->h_{2}[n]------>y[n]

with h_{2}[n]= s[n] - s[n-1];

and i am suppose to find h_{1},

i used the the associativity of the convolution to have another form of the problem but

what i dont understand is the information given by the equation h2 [n]

how am i suppos to use it.

the i will make the aatempt to a solution and post it.
