A local oscillator is used in a superheterodyne radio circuit for example.The incoming radio frequency is mixed with an internal local oscillator circuit to generate a new intermediate frequency (IF) .The local oscillator usually runs at a frequency of 470kHz and is generated by an inductor and capacitor(LC oscillator)

Damped (or free) oscillation occurs when an object is set to vibrate at its natural frequency while forced oscillation involves the application of a force to keep an object in constant or repetitive motion.

Oscillation Isolator was created in 2009.

NO,oscillation is not necessarily a wave because energy is not transported in oscillation.In oscillation there is no space periodicity.An oscillation is periodic in time only where as a wave is periodic in time and space both.

An oscillation in which the amplitude remains constant with respect to time.

center of oscillation means the point at the pendulum which oscillate by making higher displacement through it than other points.
