Why Is FM Radio Broadcasting Still Using Analog Technology?
[ad#250 x 250 Sqr Adsense]FM radio is a broadcasting technology which has had widespread popularity and is widely used in all the regions of the world. Obviously, there are changes in frequency modulation in different areas but the core principle of its operation remains the same everywhere. However, it is quite disappointing to observe that despite constant changes in the sophistication of various technologies, like moving from analog to digital broadcasting for television channels and other services; radio has been highly neglected. The question that arises is why has it not experienced more sophistication in its technology like other broadcasting services?
The answer lies in the fact that we use radio spectrum for digital video broadcasting in television. These radio frequency spectra are used to transmit digital multiplex, which is a bundle of various television channels and other services by using 6-8 MHZ of bandwidth. Obviously, in terms of usage, digital broadcasting in television is making more efficient use of radio frequency spectrum as compared to analog broadcasting, which used the same bandwidth to broadcast only one program. This justifies the change in technology. At this important to mention that radio technology can be moved from analog to digital but it will take years to switch and grand scale technological preparations to make it happen.
There are many digital sound broadcasting technologies present that can provide good sound output with good reception like T-DAB, DRM+, DVB-T, DRM and DVB-T2; but none of these is satisfactory enough so as to replace the analog radio broadcasting. It is important to thoroughly take into account various technological aspects before switching from one technology to another. Factors like the new technology’s ability to provide good quality sound output, ability to receive signals and most importantly, its capacity to make efficient use of radio spectrum by broadcasting more radio channels.
FM radio employs 250 kHz bandwidth with spacing of 100 and 200 kHz, varying as per the region. It is because of this changed combination of bandwidth and spacing that switching from analog to digital in radio broadcasting would be difficult. Hence, we have to remain contented with the analog radio transmission unless the sophistication of the technology rises!
In the end, it is significant to mention that up-gradation in scientific technology is not a matter of a few months or decisions of a small organization. Rather, many years efforts, time investment, financial investment and consistent dedication are required for a technology to switch from its current level to a higher level. Sophistication in technology is highly desired by all in various fields, because it not only results in provides comfort to the users but also becomes a source of pride to the inventors. The same is the case in upgrading radio technology but the other factors which are currently making the switch from analog to digital technology can also not be neglected.
