  • 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
