Injection locking — is a high frequency (usually RF, but possibly microwave and optical) phenomenon where an oscillator directly synchronizes to another high frequency signal. In the case of a VCO an injection locking signal may override its low frequency control… … Wikipedia
Frequency divider — A frequency divider, also called a clock divider or scaler or prescaler, is a circuit that takes an input signal of a frequency, fin, and generates an output signal of a frequency: where n is an integer. Phase locked loop frequency synthesizers… … Wikipedia
Beat frequency oscillator — A beat frequency oscillator or BFO in radio telegraphy, is a dedicated oscillator used to create an audio frequency signal from carrier wave transmissions to make them audible, as they are not broadcast as such. The signal from the BFO is then… … Wikipedia
Current injection technique — The current injection technique is a technique developed to reduce the turn OFF switching transient of power bipolar semiconductor devices. It was developed and published by Dr S. Eio of Staffordshire University (United Kingdom) in 2007.… … Wikipedia
Fuel injection — Fuel rail connected to the injectors that are mounted just above the intake manifold on a four cylinder engine. Fuel injection … Wikipedia
DC injection braking — DC injection brake module [1] DC injection braking is a method of slowing AC electric motors. A DC voltage is injected into the winding of the AC motor after the AC voltage is disconnected, providing braking force to the rotor [2] … Wikipedia
