I got many exercises where I have to determine the response of a system to an input signal
The only things i have are the impulse response and the input signal. I was thinking I could use the convolution to get the output, but to proceed that way I should know the system is linear and time invariant, none of which is specified
Is there a way to determine if a system is whether LTI or not by knowing the impulse response?
As an example I have this exercise right here
What is the response to the input signal $x[n]=2^n u[n]$
Knowing the impulse response is $h[n] = u[n]$
More than resolving this particular problem I'm concerned on how to proceed in general when I get those type of exercises
