1. a sinusoidal oscillation which decaying exponential; the system is therefore stable.
2. a sinusoidal oscillation with time multiplier the system is therefore unstable.
3. a sinusoidal oscillation which rises exponentially with time; the system is therefore unstable.
4. a dc term and harmonic oscillation; the system therefore becomes limitingly stable
