Demodulation does not have disadvantages per say, but it does have a lot of complexities. FM recording circuitry is more complicated than that of direct recording systems. If the amplitude modulated signal is weak, the receiver requires a complex arrangement. Thus FM reception is immune to noise than AM reception. It is in between LAN and WAN technology and that cover the entire city. When high frequency (HF) is not needed, and with a view to conserving tape. In FM if there are two or more signals received at the same frequency, the FM receiver will capture the stronger signal and eliminate the weaker signal. This is serious drawback of FM. The lower frequencies of the band we use for AM signals creates a wavelength that is extremely large. It requires a bandwidth equal to twice that of the highest audio frequency. It is an important step of communication system. FM recording circuitry is more complicated than that of direct recording systems. Explanation: The disadvantage of FM over AM is that in frequency modulation large bandwidth is required. Skip distance is defined as the minimum distance from the earths surface and the point from where the radio signal is transmitted. Phase Modulation Frequency Modulation: (Definition & Introduction) The central frequency is selected with respect to the tape speed and frequency deviation selected for the tape recorders is 40% about the carrier frequency. This is another reason why FM systems are costlier than AM systems. This type of system is mostly used for Digital recording. AM stands for Amplitude modulation, the amplitude of the RF carrier is varied in accordance with the amplitude of modulating signal input.
