Hệ thống LTI nhân quả với tín hiệu vào x ( n ) , tín hiệu ra nhận được là y ( n ) . Tìm h ( n ) x ( n ) = { 0 , 2 _ , 1 , 2 , 0 } ; y ( n ) = { 0 ,

$\text{h}\left(\text{n}\right)=2\delta \left(\text{n}\right)+\delta \left(\text{n}-1\right)+2\delta \left(\text{n}-2\right)$

$\text{h}\left(\text{n}\right)=2\delta \left(\text{n}\right)+2\delta \left(\text{n}-1\right)+\delta \left(\text{n}-2\right)$

$\text{h}\left(\text{n}\right)=2\delta \left(\text{n}\right)+2\delta \left(\text{n}-1\right)+2\delta \left(\text{n}-2\right)$

$\text{h}\left(\text{n}\right)=2\delta \left(\text{n}\right)+3\delta \left(\text{n}-1\right)+\delta \left(\text{n}-2\right)$
