The impulse response of a LTI system is h(n)={1,1,1}. What is the response of the signal to the input x(n)={1,2,3}?
A. {1,3,6,3,1}
B. {1,2,3,2,1}
C. {1,3,6,5,3}
D. {1,1,1,0,0}
Answer:A
The impulse response of a LTI system is h(n)={1,1,1}. What is the response of the signal to the input x(n)={1,2,3}?
A. {1,3,6,3,1} B. {1,2,3,2,1} C. {1,3,6,5,3} D. {1,1,1,0,0}
Explanation: Let y(n)=x(n)*h(n)(‘*’ symbol indicates convolution symbol)
