How can moving a car up or back a few meters make a difference to radio reception?
because it interferes with radio waves signals that are transfering from one place to another
Why is the car radio affected by the receipt of a text massage on a mobile in close proximity?
The antenna is picking up the transmission of the signal, and then amplifying it. It could be blocked by having a bandpass filter placed at the point where the antenna comes into the radio Because the frequency of the signal of the mobile interferes with the radio reception. Moreover, the signal of the mobile is strong enough to produce noise on all frequencies range of the radio. Even electric motors can produce noise when next to a radio receiver.
What are Irregular fluctuations which tend to obscure electrical signals or radio reception also called static?
White noise
Are sunspots good or bad?
They are bad for the people on the planet Earth that want to listen to radio, watch TV, or communicate, since sunspot activity interferes with RF transmission and reception.
Radio reception improves after sunset-why?
If you mean FM/AM radio: Radio reception is based off the bouncing of radio waves off of the upper atmospohere and ionosphere. But in the daylight, the sun causes molecular turbulence in those layers like photodissociation and infrared absorption. Imagine trying to look in a liquid mirror that has a lot of turbulence vs one that is rather stagnant. Sunlight makes the "mirror" of the upper atmosphere and ionosphere turbulent while in comparison the night sky is a more stagnant "mirror" Particularly, radio stations switch to low power mode some point after dark because of the substantial increase in transmission-reception ability. ---- If you mean radio astronomy: Your question is better stated, "why does the signal-to-noise ratio improve after sunset" where "improve" means "increase". Though it is not as dramatic as the visible or infrared emissions, the sun is a strong radio source. As a result, if we are looking for radio signals that are not the sun, then the sun is considered to be part of the background noise. Then after sunset, this noise source is propagating through the earth and not directly into the radio telescopes. As a result, the amplitude or level of noise has decreased and the signal has remained mostly the same and thus the signal-to-noise has increased by dividing by a smaller noise. signal-to-noise is literally "signal divided by noise".
What are the noise factors for radio tv and audio systems?
The measurements include Signal to Noise Ration (dB), Total harmonic distortion (%) and Channel crosstalk (dB).
Which brand of car cassette player gets the best radio reception?
Sanyo's are known for their radio reception.
Does diffraction hinder radio reception?
Diffraction helps rather than hinders radio reception. Computers, monitor screens, and halogen lights are examples of things that can hinder radio reception.
The radio reception fades in and out on your Mercedes 2000 S430?
The radio adjust automatically to the amount of road noise, more noise, the radio adjust its volume, and of course, that works the same way reversed, lesser noise, lower volume needed. Test this by opening your windows while driving on the freeway, the radio adjust its volume up, so you be able to listen to the music, by closing the windows, the volume automatically turns down.
Which clock radios have the best radio reception?
Sony, Emerson, Timex and RCA all have excellent radio reception.
How do you say reception in french?
Reception in French is réception or accueil. réception= radio signal, reception accueil= welcome, reception
What causes noise?
Before anyone can give a sensible answer to this question, whoever asked it should please log in and edit the question to explain what exactly what "noise" is being asking about. Noise in the street? Noisy hi-fi systems? Noisy reception in a radio? Picture noise in a television?
