DAB+

Hallo all wise people out there.
I heard a DAB+ receiver the other day.
And if we just let the DAB part be, The sound was just like CD when it was new.
Obviously some sensational bad analog stages.
So is there som documentation on the circuitry in DAB receivers?
Both principal block schematics and which chip manufacturers make good solutions.

Here it was discussed, with a link to a service manual:

DAB+ is unlikely to sound like CD because DAB+ uses lossy compression. Better than DAB, but will always be worse than CD.

It depends on the bitrate used by the radio stations in your country. Some countries use such a low bitrate that analogue FM is much better.

FM is worse than CD, but better than DAB+.

So the rank is:

CD (digital) > FM (analog) > DAB+ (lossy compressed digital)

 

[Foxx510]

So the rank is:

CD (digital) > FM (analog) > DAB+ (lossy compressed digital)

It depends on the bitrate used. I'm not sure if any countries use high enough bitrates to outdo analogue FM or not.

DAB+ sound quality can not be better than FM, regardless of bitrate. DAB+ standard has its own limits.

Well, all opinions are OK, but I need a description of the DAB+ system.
