The simplest mechanical oscillating system is a weight attached to a linear spring subject to o… 展开

In two or three dimensions, harmonic oscillators behave similarly to one dimension. The simplest example of this is an isotropic oscillator, where the restoring force is proportio… 展开

Phase portrait of damped oscillator, with increasing damping strength. All real-world oscillator systems are thermodynamically irreversible. This means there are dissipative proce… 展开

In addition, an oscillating system may be subject to some external force, as when an AC circuit is connected to an outside power source. In this case the oscillation is said to be driven. The si… 展开
