Teaching TN TRB EC Mock Test Signals and Systems Linear Time Invariant Systems Properties of LTI Systems
A Linear Time Invariant system with an impulse response h(t) produces output y(t) when input x(t) is applied. When the input x(t – τ) is applied to a system with impulse response h(t – τ), the output will be
1
y(τ)
2
y( 2 (t – τ) )
3
y(t – τ)
4
y(t – 2τ)
