-- FM is better for the person on the transmitting end, because it's easier and cheaper to
generate with high quality. Modulation can be applied in an early stage of the transmitter,
at low frequency, low power, and with a small modulation index, and the final signal for
transmission can be derived by frequency multiplication and power amplification, without
garfing up (corrupting) the signal and producing a lot of intermod. AM must be modulated
at the final frequency and power, which requires half as much audio power as final carrier
output power, which is expensive.
-- FM is better for the person on the receiving end, because most of the radio noise in
nature, as well as man-made radio noise, is amplitude noise. If your receiver doesn't
care about changes in amplitude, it's immune to a lot of the noise that gets picked up
on the way from the transmitter to the receiver.
What else can I help you with?
What are the advantages frequency modulation amplitude modulation?
Frequency modulation have some advantages over amplitude modulation, FM is not sensitive to the amplitude noise, and have high efficient use of transmitted power
What does FM stand for in radio frequency?
FM means Frequency Modulated.FM stands for modulation on frequency or frequency modulation.
What is the difference between frequency modulation and phase modulation?
The difference between frequency modulation and phase modulation is that with frequency modulation the angular frequency of the signal is modified while with the phase modulation, the phase angle of the signal is modified.
What does AM and FM stand for in radios?
AM - Amplitude Modulation FM - Frequency Modulation
What is the significance of the delta f over f parameter in frequency modulation?
The delta f over f parameter in frequency modulation is significant because it represents the frequency deviation relative to the carrier frequency. It determines the amount by which the frequency of the modulated signal varies from the original carrier frequency. This parameter is crucial in determining the bandwidth and quality of the modulated signal in frequency modulation systems.
What is Modulation index in 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
Which of the following modulation is non linear?
frequency modulation is non linear due to cross over term.
What is the meaning of FM in FM Radio?
FM means frequency modulation AM means amplitude modulation
What is the relationship between frequency modulation and the frequency carrier to the modulation index in the AM modulation?
fc>2fm
When modulation frequency is double the modulation index is halF and the modulating voltage remains constant the modulation system is?
frequency modulation..
What is modulated frequency?
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.
Define modulation and modulation index?
a measure of the degree of frequency modulation expressed numerically for a pure tone modulation as the ratio of the frequency deviation to the frequency of the modulating signal.
