The central idea of a writing is the theme.
AM has a frequency range of 531 kHz to 1602 kHz and on the other hand FM has a frequency range between 8705 MHz to 108 MHz. If we talk about the bandwidth of AM then it is 1071 KHz and bandwidth of FM is 20.5 MHz.According to the bandwidth FM should be used for long distance transmission but it is not used for long distance but AM is used fir long distance transmissions. the answer is here.Long distance transmissions are also decided by the Spectrum of the Signal in frequency domain by doing the Fouriertransform of the Signal.If we draw the Spectrum of AM waves the we find that their is a main loop in the central part of the spectrum with a high frequency and on the left and right side of this loop their are side loop which are very smaller then the main loop. In FM information can be recover from the main loop only not from the side loops. On the other hand in AM waves all the loops in spectrum is of same size and information can be recover from all the loops.That is why AM is used for long distance transmission.Thnx -Vipin Jasoria

You can learn to install a central heating thermostat on Energysavingtrust. You can also learn how to do it on Doityourself. These websites teach you how to install a central heating thermostat.
Out-band rejection is often exprerssed in dB. It is a important characteristic for a passive bandpass filter or an active LNA. One can use the network analyzer or spectrum to measure the out-band rejection by setting the instrument to the desired frequency. You can see the power level "out of" the central frequency and such power levels in different frequencies are the corresponding out-band rejections (in dB).

Most of central Berlin was in ruins in 1945. Even the houses that were still standing, were usually heavily damaged. The total percentage of ruined and heavily damaged houses was close to 100%.

the percentage of what??? check the central statisitcs office ireland, they have data from the 2006 and 2002 census freely available along with some other information.
