fc>2fm
it varies from carrier to carrier and it's different for each person
If you look at the carrier you will see a big pin that goe's through the spider gears and carrier. Turn the carrier around until you see a small bolt on the right side of it. Remove the bolt that is what holds the pin in the carrier. Then pull the pin out towards you. Then push the axel's in and the c-clips will fall out. Then put pin back in so the spider gears don't fall out.
Microwaves are used in communications because of their shorter wavelength and smaller antennae. This allows them to be more directional than lower frequency radio waves. The Microwave spectrum also has more bandwidth than the radio spectrum. They also waste less energy than Radio Waves
NADP
yes, a very good one actually
Amplitude of the (high frequency) Carrier signal is varied with respect to low frequency of message signal is called amplitude modulation. Frequency of the carrier signal is varied with respect to low frequency of message signal is called frequency modulation.
Modulation Index is the ratio of the maximum deviation frequency to the frequency of modulation. In other words it is the ratio of the spread in frequency spectrum to the frequency that was used to modulate the carrier. For FM, modulation index is given by the formula mf= df/f where, mf=modulation index for FM df=difference in carrier frequency f=frequency of the signal
in frequency modulation, frequency of carrier signal changes. so frequency variations of carrier convey all the information in frequency modulation.
A: A carrier carry information by modulation either Amplitude or Frequency modulation. Therefore AM and FM RADIO M stand for modulation
FM stands for frequency modulation. The definition is: when the frequency of the carrier wave is changed in accordance with the intensity of the signal, it is called frequency modulation. In frequency modulation, only the frequency of the carrier wave is changed in accordance with the signal. However, the amplitude of the carrier wave remains unchanged.
In a analog transmitter the RF carrier have to be modulated with the analog signal either by AM or FM where in digital transmitter the carrier is simply switched on and off a off = a zero and on = a one
frequency modulation stands for FM (on your radio).Better Answer"frequency modulation stands for FM"No it doesn't. On the contrary, f.m. stands for frequency modulation.Frequency modulation is the method of impressing information on an r.f. carrier by changing its frequency back and forth in sympathy with the informatiion signal.
Deviation ratio: In a frequency modulation system, the ratio of the maximum frequency deviation of the carrier to the maximum modulating frequency of the system under specified conditions
probably (the carrier frequency +- the maximum frequency of the pulse train)/(the carrier frequency) but pulses have a lot of harmonics
Frequency modulation and Phase modulation
Deviation ratio: In a frequency modulation system, the ratio of the maximum frequency deviation of the carrier to the maximum modulating frequency of the system under specified conditions
Maximum frequency deviation occurs in frequency modulation (FM) when the modulating signal reaches its peak amplitude. This deviation represents the greatest difference between the carrier frequency and the modulated frequency. In practice, it corresponds to the point where the instantaneous frequency of the carrier signal varies the most due to the modulation, often occurring at the maximum input signal level.
