WebW.1.8 Parametric Oscillations. Parametric oscillation occurs when one of the parameters of the system is varied. A child can "pump" a swing by standing and raising and lowering her center of mass periodically, changing the length of the pendulum.The child pumps at twice the pendulum frequency, generating a sub harmonic.. A very simple demonstration of … A parametric oscillator is a driven harmonic oscillator in which the oscillations are driven by varying some parameter of the system at some frequency, typically different from the natural frequency of the oscillator. A simple example of a parametric oscillator is a child pumping a playground swing by periodically … See more Parametric oscillations were first noticed in mechanics. Michael Faraday (1831) was the first to notice oscillations of one frequency being excited by forces of double the frequency, in the crispations (ruffled surface waves) … See more A parametric oscillator is a harmonic oscillator whose physical properties vary with time.
