high frequency oscillation meaning

• [Medicine]
  Ventilatory support system using frequencies from 60-900 cycles/min or more. Three types of systems have been distinguished on the basis of rates,volumes,and the system used. They are high frequency positive-pressure ventilation (HFPPV); HIGH-FREQUENCY JET VENTILATION; (HFJV); and high-frequency oscillation (HFO).

• A bias tee is needed to isolate the bias current from the high frequency oscillations.
• Synaptic noise has been associated with high frequency oscillations ( HFOs ) within the brain.
• This causes high frequency oscillations of the pressure sensor ( approx 200 kHz for a Kistler 6215 transducer ) and this requires Butterworth ).
• In the alternate circuit, high amplitude high frequency oscillations that appear across the capacitor also are applied to the supply transformer's winding.
• Challenges to successful nantenna technology include fabricating an antenna small enough to couple optical wavelengths, and creating an ultrafast diode capable of rectifying the high frequency oscillations.
• In 1904 Fleming tried an Edison effect bulb for this purpose, and found that it worked well to rectify high frequency oscillations and thus allow detection of the rectified signals by a galvanometer.
• A "'Boucherot cell "'( or "'Zobel network "') is an electronic filter, used in audio amplifiers to damp high frequency oscillations that might occur in the absence of loads at high frequencies.
