Question 1
A system is described by the described by the difference equation
y[n] = x[n] – x[n – 2]+ x[n – 4] – x[n – 6]
The impulse response of system is
Question 2
Let x[n] = δ[n – 1] + δ[n + 2].
The unilateral z-transform is
Question 3
The time signal corresponding to is
Question 4
An L.T.I system with input x(n) = {2, 4, 6, 8, 10, 12} produces the output as {1, 3, 5, 7, 9, 11, 6}. Then the impulse response is ……………
