• Frequency synthesizer — A frequency synthesizer is an electronic system for generating any of a range of frequencies from a single fixed timebase or oscillator. They are found in many modern devices, including radio receivers, mobile telephones, radiotelephones, walkie… …   Wikipedia

• Frequency counter — A frequency counter is an electronic instrument, or component of one, that is used for measuring frequency. Since frequency is defined as the number of events of a particular sort occurring in a set period of time, measuring it is usually… …   Wikipedia

• Frequency changer — A frequency changer or frequency converter is an electronic device that converts alternating current (AC) of one frequency to alternating current of another frequency. The device may also change the voltage, but if it does, that is incidental to… …   Wikipedia

• Parametric oscillator — A parametric oscillator is a simple harmonic oscillator whose parameters (its resonance frequency omega and damping eta) vary in time in a defined wayAnother intuitive way of understanding a parametric oscillator is as follows: a parametric… …   Wikipedia

• Intermediate frequency — In communications and electronic engineering, an intermediate frequency (IF) is a frequency to which a carrier frequency is shifted as an intermediate step in transmission or reception. The intermediate frequency is created by mixing the carrier… …   Wikipedia

• Blocking oscillator — A blocking oscillator is the minimal configuration of discrete electronic components which can produce a free running signal, requiring only a capacitor, transformer, and one amplifying component. The name is derived from the fact that the… …   Wikipedia

• Image frequency — Image frequency: In radio reception using heterodyning in the tuning process, an undesired input frequency that is capable of producing the same intermediate frequency (IF) that the desired input frequency produces. In a heterodyne receiver… …   Wikipedia
