Sine | [[Sine Wave]] oscillators can also be classified by frequency, or the type of frequency control they use. RF (radio frequency) oscillators working at frequencies above about 30 to 50kHz use LC (inductors and capacitors) or Crystals to control their frequency. These may also be classified as HF, VHF, and UHF oscillators, depending on their frequency.<ref>[http://www.learnabout-electronics.org/Oscillators Oscillators]</ref> | ||
