This paper presents the design and implementation of a digital audio broadcasting (DAB) signal analyzer. It can be used to test transmitter products or to learn the DAB technique. Compared to conventional DAB receivers, it provides more information of the signal and it is much cheaper than professional analyzers. Several key blocks are described in details such as synchronization and offset correction. The system has been tested with real DAB signal and works well.
