DAB (Digital Audio Broadcasting), also known as digital
radio, is a new way of radio broadcasting. DAB is
broadcast using digital signals instead of analog signals,
resulting in near CD-quality sound. Analog signals (i.e.
AM/FM) are susceptible to interference (i.e. distortion and
noise) caused by electrical equipment, weather conditions,
tall buildings, mountains, etc.; digital signals are not.
Thus, with DAB, there is virtually interference-free
reception and no hiss or crackle.
