railway RRB JE (CBT I + CBT II) Mock Test 2024 Signals and Systems Discrete Time Signals and Systems Characteristic of Systems
The input x(t) and output y(t) of a system are related as
\(y(t) = \int\limits_{ - \infty }^t {x\left( t \right)} \cos \left( {4t} \right)dt\)
The system is
1
time - invariant and stable
2
stable and not time - invariant
3
time - invariant and not stable
4
not time - invariant and not stable
