Discussion oscillators

ÿ
Oscillators that use an LC feedback circuit use an inductor and ÿcapacitor feedback to oscillate the output.ÿ These oscillators use a ÿtuned tank circuit on the collector side of the amplifier.ÿ The inductor ÿof the tank circuit is electromagnetically coupled with another ÿinductor (like a transformer) which is across the base and emitter.ÿ A ÿchange in current flow on the tank circuit induces an electromagnetic ÿfield in the base-emitter inductor which makes the two current flows to ÿbe 180 degrees out of phase with each other.ÿ This causes an sinusoidal ÿOscillation on the output.ÿ This type of oscillator mainly used for ÿRadio Frequency (RF) applications that require a high frequency sine ÿwave.

The FAA encourages its flyers to turn off devices during take-off and ÿlanding due to the possible interference with navigation, radar, ground ÿcommunication, and collision avoidance systems.ÿ Although most phones ÿare not capable of emitting strong enough RF waves to interfere, devices ÿlike Ipods, Laptops, and handheld gaming consoles can emit strong ÿenough RF waves to interfere with these systems, especially in confined ÿspaces.ÿ In this case, if these RF waves were to make its way to these ÿsensitive devices, it is more than capable of causing false reads and ÿpossible act as a jammer in a sense which definitely would not be good ÿfor anyone on the plane if this were to happen at these critical ÿmoments.
