Why FM is more clearer than am?
The abbreviations FM and AM stands for amplitude modulation and frequency modulation. The reason why FM is more clearer than AM is because FM has a better signal-to-noise ratio than AM does.
What type of radio receiver do not respond to static interference?
FM radio is inherently less sensitive to natural noise ... not immunebut significantly less sensitive ... than AM radio is.
What are four FM radio stations?
Peace FM in Ghana,Joy FM,love FM and Spirit FM
What the strongest FM signal booster?
The effectiveness or strength of FM signal boosters is roughly measured in "db". Db means decibels, a measure of signal strength above noise. A quick search revealed boosters for sale ranging from 14db to 25db. More db = stronger.
What came first am. of fm.?
fm
What is FM threshold effect?
An important aspect of analogue FM satellite systems is FM threshold effect. In FM systems where the signal level is well above noise received carrier-to-noise ratio and demodulated signal-to-noise ratio are related by: The expression however does not apply when the carrier-to-noise ratio decreases below a certain point. Below this critical point the signal-to-noise ratio decreases significantly. This is known as the FM threshold effect (FM threshold is usually defined as the carrier-to-noise ratio at which the demodulated signal-to-noise ratio fall 1 dB below the linear relationship given in Eqn 9. It generally is considered to occur at about 10 dB).
Why FM is mostly preferred to AM in telecommunication?
Nature creates AM noise (static) so FM is clearer
What modulation technique used in tv broadcasting?
AM and FM
What is noise triangle?
Noise triangle is a triangular noise distribution for FM.Noise triangle is the study of effect of noise on the carrier signal of the FM wave.
Noise reduce from signal?
noise reducing from signal by some method?
Why FM is more clearer than am?
The abbreviations FM and AM stands for amplitude modulation and frequency modulation. The reason why FM is more clearer than AM is because FM has a better signal-to-noise ratio than AM does.
What of the three analog-to-analog conversion techniques AM FM or PM is the most susceptible to noise?
AM is most susceptible to noise.
What type of antenna is used in cellphone for FM?
LNA - Low Noise Amplifier
What is noise triangle and effects of noise on carrier?
Noise triangle is a triangular noise distribution for FM.Noise triangle is the study of effect of noise on the carrier signal of the FM wave. for more details contact -Ameya Muley (amymuley@rediffmail.com)
What filming technique involves increasing or reducing the intensity of a picture?
say it
Why does the FM radio wave remain unaffected by such a plasma?
Just about all radio noise is amplitude modulated. FM radios use Frequency Modulation and is unaffected.
Why is FM superior immunity to noise?
FM systems are far better at rejecting noise than AM systems. Noise generally is spread uniformly across the spectrum (the so-called white noise, meaning wide spectrum). The amplitude of the noise varies randomly at these frequencies. The change in amplitude can actually modulate the signal and be picked up in the AM system. As a result, AM systems are very sensitive to random noise. An example might be ignition system noise in your car. Special filters need to be installed to keep the interference out of your car radio. FM systems are inherently immune to random noise. In order for the noise to interfere, it would have to modulate the frequency somehow. But the noise is distributed uniformly in frequency and varies mostly in amplitude. As a result, there is virtually no interference picked up in the FM receiver. FM is sometimes called "static free, " referring to its superior immunity to random noise.
