railway RRB JE (CBT I + CBT II) Mock Test 2024 Signals and Systems Linear Time Invariant Systems Convolution of Signals
The impulse response of a linear time invariant system is h(n) = {1, 2, 1, -1}. The response for the input signal x(n) = {1, 2, 3, 1} is
1
{1, 8, 4, 8, 3, -1, -2}
2
{1, 4, 8, 3, 8, -2, -2}
3
{1, 4, 8, 8, 3, -2, -1}
4
{1, 8, 3, 8, 8, 4, -1}
