What is near-far effect?
Adjacent channel interference nearby frequency leak into passband. The problem can be worse if an adjacent channel user is transmitting in very close range to a subscriber receiver. This problem is referred as near far affect. By Kazi Ashique Ahmed Rafi it usaully occurs in CDMA when users are transmitting unequal powers. by salman ahmed

What is the importance of De-emphasis network in FM receiver?
One characteristic of the FM process is that the noise is distributed such that it's lowest at the bottom frequency of the channel, and increases steadily as you move up the channel. Knowing this, pre- and de-emphasis is the clever trick we use to decrease the noise in the FM communications channel. Here's how it's done:At the transmitter, pre-emphasis is applied to the baseband information before modulation ... the main channel L+R and L-R signals, plus any subcarriers that the station carries. Pre-emphasis is intentional distortion of the frequency response across the baseband that attenuates the low-frequency end, and progressively amplifies everything as you move up in frequency. The result of this operation is what actually gets transmitted.The receiver is responsible for doing just the opposite. It applies de-emphasis immediately after demodulation ... it attenuates the high-frequency end of the baseband, and progressively amplifies everything as you move down in frequency.If the pre- and de- are accurately matched, then the frequency response of the system winds up flat across the baseband, which is what we want. But ... by attenuating the higher frequencies, the receiver also changes the noise-content of the baseband, from a distribution that gets worse as you move up in frequency, to a distribution that's flat across the channel.
A radio station's channel such as 100.7 FM or 92.3 FM is actually its frequency in megahertz where Calculate the broadcast wavelength of the radio station 104.9 FM?
Wavelength = Speed of light/frequency Wavelength= 300'000'000/104'900'000 (FM 104.9 is frequency modulation 104.9 MHz) Wavelength=2.86 meters
