Electrical Engineering > GATE 2021 > LTI Systems
Two discrete-time linear time-invariant systems with impulse responses h1[n]=δ[n-1]+δ[n+1] and h2[n]=δ[n]+δ[n-1] are connected in cascade, where δ[n] is the Kronecker delta. The impulse response of the cascaded system is
A
δ[n-2]+δ[n+1]
B
δ[n-1]δ[n]+δ[n+1]δ[n-1]
C
δ[n-2]+δ[n-1]+δ[n]+δ[n+1]
D
δ[n]δ[n-1]+δ[n-2]δ[n+1]

Correct : c
