Parametric Amplifiers and. Oscillator. A device exhibiting a negative conductance, such as a tunnel diode, can be utilized to ... frequency components of signal, idler and pump waves in such a nonlinear element

Answer 2

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 standing and squatting to increase the size of the swing's oscillations.[1][2][3] The child's motions vary the moment of inertia of the swing as a pendulum. The "pump" motions of the child must be at twice the frequency of the swing's oscillations. Examples of parameters that may be varied are the oscillator's resonance frequency ${\displaystyle \omega }\omega \: and \: damping \: {\displaystyle \beta }\beta .$
