This carrier is separated at receiver by an appropriate filter, is amplified, and is used to phase lock the locally generated carrier at the receiver. Hence, most music is broadcast over FM radio. The carrier source produces carrier signal. Any sound produced is basically a series of vibrations that travel through the air in form of a ‘Transverse wave‘ i.e. While the speed of it does depend on where you live, it 's generally much easier and faster to download things as you get much faster speeds than with mobile broadband. Hence the effects of noise are minimized in FM. Letus discuss aboutthe Dual Beam Oscilloscope: vi) Line-of-sight (LOS) based restrictions in transmission do not present themselves. Following are some of the advantages for implementing modulation in the communication systems. The change or shift above or below the mean or centre frequency is called the frequency deviation. It is used to find out the velocity of a target by removing Doppler data. Any variation in signal level does not affect the output as long as the receiver is able to cope up with the signal level. The total variation in frequency from minimum to maximum value is called the carrier swing and it is twice the frequency deviation i.e CS = 2Δf. Frequency modulation is a technique or a process of encoding information on a particular signal (analogue or digital) by varying the carrier wave frequency in accordance with the frequency of the modulating signal. The bandwidth of the frequency-modulated signals is higher than that of AM modulated signals that help to transmit better quality voice signals. The equipment of FM system is more complex than AM systems because of the complex circuitry of FM systems; this is another reason that FM systems are costlier AM systems. 3.

FM is a so called angle modulation scheme, it was inspired by phase modulation but has proved to be more useful partly for its ease of generation and decoding. This allows the encoders and decoders the … The advantages of phase modulation include the following. Hence Si was chosen to lead the electronics industry henceforth. When spectrum efficiency is important Narrowband FM (NBFM) is used but when better signal quality is required Wideband FM (WBFM) is used at the expense of greater spectrum usage. The advantages of FM over AM systems are: The amplitude of an FM wave remains constant. Silicon transistors were less immune to electro-magnetic interferences and weren’t then suitable for high frequency applications but that was hardly a deal breaker compared to the size reduction and minimized power consumption. The amplitude of FM is constant which makes it independent of the modulation deption, while in AM modulation depth directs the transmitted power. Frequency Modulation. What are the disadvantages of frequency modulation? Resilience to noise: One particular advantage of frequency modulation is its resilience to signal level variations. The carrier is kept in an envelope formed by the modulating wave. This site uses Akismet to reduce spam. There are two types of angle modulation. 1.

The percent modulation when applied to FM, has slightly different meaning than when applied to amplitude modulation. We all know that ‘sound’ is a form of energy. The beginning of that answer to that is what we intend to decipher in this discussion. ADVANTAGES OF MODULATION : With the help of modulation, we can increase the quality of reception. 2. Advantage – 1. 1. A frequency modulated wave shows resilience (flexibility) property towards noise and interference factor. But the good thing is that they normally come with a high quality service warranty. The wide dynamic range of a spectrum analyzer (over 70dB) allows measurement of modulation percentages as low as 0.06%. Advantages of FM. It 's also becoming more widespread, which makes it increasingly cheap. Now the audio signal is modulated onto the radio frequency carrier the new radio frequency signal moves up and down in frequency. The main advantage of FM is, it is less susceptible to noise and other interferences during transmission of signals. It can be used for low power transmitters.

Phase modulator is used in determining velocity of moving target by extracting Doppler information. ADVANTAGES OF FREQUENCY MODULATION Frequency modulation is resilient to signal level variations. FM radio systems employ frequency modulation of the carrier wave to encode information. Both these cycles are varied according to the information to be sent. Fundamentally, amplitude compression function is the task of controlling the overall gain of a speech amplification system. The use of non-linear amplifiers, e.g. The vacuum tubes had an operational advantage over the Si transistors purely because the electron mobility is better in vacuum than in Si. Saturation power is where the sound signal begins to become uncomfortable. The ratio of maximum permitted frequency deviation to the maximum permitted audio frequency is known as the deviation ratio. Silicon first replaced the vacuum tube transistor mainly for their unusually large size and the excessive power consumption. In the earlier time of wireless communication, it was measured that the required bandwidth of this was narrower, and necessary to decrease noise as well as interference. Angle modulation is a technique in which the angle of the carrier wave is varied according to the instantaneous amplitude of the modulating signal. But at high noise densities the window size has to be increased which may lead to blurring the image. This needs constant carrier which is achievable during phase modulation however not in FM (frequency modulation). Frequency Modulation 2. Less sensitive to Noise; Large signal to noise ratio; Amplitude of signal does not change; Resilience to variation in signal strength; Resilience to interference when deviations are much greater than the highest modulating frequency; Capture effect (Only th strongest signal on the receiver frequency gets through) With the help of the modulation, we can set the band limits example X communication band is 250 – 300 MHz and for Y it’s 300 – 350 MHz so that we can easily add and subtract various communication supplier. This one advantage of the f-m system counts heavily in its favor and, even if there were no others, would be sufficient justification for its use. Disadvantages For an expected output, less battery power is required and thus can be used for two-way radio applications. i) One of the biggest disadvantages to radio communication technology is the limited range of a radio signal.
