Another example is a pharmaceutical liquid handling instrument with unexpected vibrations that agitate the transported liquid solution. For example, a CNC milling machine (which typically has a high resonant frequency due to high stiffness)  will jitter around the desired milling path if a resonant frequency is excited. The overall range of resonant frequencies of the human body was found to be from 62 to 68 Hz and independent of mass, height and mass to height ratio. When the switching frequency is varied, the stored energy can be varied for each cycle and hence the voltage output is varied. When the L and C are placed in parallel or series, they have a resonant frequency. LC circuits consist of two connected electronic components: the inductor (L) and the capacitor (C).
