And CD-quality sound system
AM and FM radio than DAB / traditionally has many advantages. Compared with normal DAB FM radio, with superior quality sound. Other external sources DAB interference. However, DAB has a unique capability for mobile users, providing high-quality coverage wherever and whenever needed.
Spectral Efficiency
Another important advantage of the DAB spectrum efficiency. This means that there are proper ways to increase the number of BTS. DAB can be a relationship between the band jams do not occur at least three FM radio waves. Audio coding method is more effective, may produce more without changing the existing radio receiver, no reduction in existing services.
Valid comments
DAB has the ability to increase the echo signal has been received directly constructive passive. You can also use Active echo. Between the transmitter does not have a special place in the delay. This is called Single Frequency Network (SFN) for the concept. In frequency and time, a network-frequency transmitter that must be synchronized in all conditions. Another important concept is the technology to fill the gap. Applications on behalf of the second category, thus taking advantage of the concept of environmental protection. Normal load, receive signals from the main transmitter and broadcast the same frequency at low power. Although the main transmitter and filter time there are some differences. The concept of interest, in both terrestrial and satellite systems flexible. Minister of Transportation, on the road, the driver must re-adjust their movement signal from the transmitter to another receiver.
DAB solve this problem, because these two concepts, modern network and frequency to fill the gap.
