Digital Audio Broadcasting 

(DAB) is revolutionizing how the world listens to music, news, sports, traffic/weather and local content.

Many similar acronyms abound such as DMB (Digital Multimedia Broadcasting), DAR (Digital Audio Radio), DRB (Digital Radio Broadcasting), and DSB (Digital Sound Broadcasting).

Whether designing equipment for in-band on channel (IBOC) or out of band (OBOC) circuits, Eureka-147, USADR, or ISDB-TN standards, engineers require robust and only the highest quality frequency components to discriminate and lock a satellite or terrestrial signal at possibly high speed and in a variety of environments.
