Forcing function
editTalk:Active-filter tuned oscillator
The roots of the characteristics equation can be found by solving the differential equation.

The characteristic equation explanation:

Phase Shift
editPhase shift can happen in other frequencies and total loop phase shift = 180°. http://web.ics.purdue.edu/~ebaytok/projects/Oscillator.pdf
Unstable system
editWith sinusoidal excitation feedback from the controlled voltage feedback which is greater or equal to the reference input at any frequency, the system is unstable.

Oscillation
editThe crystal used for micro controller or any ICs can generate pulse trains and information can go inside the IC by that pulse train.
