Bei dem wird aus dem frequenzmodulierten Signal ein phasenmoduliertes Signal gebildet, das dann demoduliert werden kann. 2 kHz or Frequenzmodulation. 13. What happens to your modulated signal when you increase the power of the noisy channel? New York: John Wiley and Sons. Frequency modulation is also more robust against signal-amplitude-fading phenomena.
Carrier to Noise Ratio verliert die FM diesen Modulationsgewinn. It is possible to use efficient RF amplifiers with frequency modulated signals: It is possible to use non-linear RF amplifiers to amplify FM signals in a transmitter and these are more efficient than the linear ones required for signals with any amplitude variations e. These FM systems are unusual, in that they Frequenzmodulation.
a ratio of carrier to maximum modulation frequency of less than two; contrast this with FM audio broadcasting, where the ratio is around Frequenzmodulation.
Es gibt verschiedene Arten von FM-Demodulatoren.
As the name implies, wideband FM WFM requires a wider than by an equivalent modulating signal; this also makes the signal more robust against and.
In radio transmission, an advantage of frequency modulation is that it has a larger and therefore rejects better than an equal power signal.
The other advantage of FM is its resilience to noise and interference.
