BetolMaybe you misunderstand. All FM transmitters are analogue by their very nature - they all transmit a frequency modulated analogue signal - but the source material (whether it is vinyl or CD) is first digitised by a 13 bit encoder before being sent to the transmitter and then decoded back into analogue for transmission. This is done to prevent losses if the transmitter is some distance away and not in perfect line-of-sight.
So the so called purity of FM includes two stages of digital conversion. Whatever is the reason for FM sounding better, it's not the method of transmission. My guess is it's limited HF bandwidth of FM and sharp birdie tone filtering at the treble end which limits the audibility of the digital arifacts you can hear so clearly on DAB.
