How is DAB digital radio different to FM radio?
DAB digital radio is different because, instead of being made up of analogue waves, the radio signal is transmitted digitally, as a series of zeros and ones. You don’t need a satellite dish to receive digital radio, just an aerial positioned in the correct place. Traditional FM analogue radio waves are sensitive to noise or distortion from electrical equipment or the atmosphere. The waves can bounce off tall buildings and hills and become interrupted or distorted.
