Practice Question on Computing the Output of an LTI system by Convolution
The unit impulse response h[n] of a DT LTI system is
$ h[n]= \frac{1}{5^n} . \ $
Use convolution to compute the system's response to the input
$ x[n]= \delta[n-3]. \ $
You will receive feedback from your instructor and TA directly on this page. Other students are welcome to comment/discuss/point out mistakes/ask questions too!
Answer 1
$ y[n]=h[n]*x[n]=\sum_{k=-\infty}^\infty \frac{1}{5^k}\delta[n-3-k]] $
$ y[n]=\frac{1}{5^{n-3}} $
