Digital dual-tuner improves radio reception in critical signal conditions

STMicroelectronics and Blaupunkt have come up with an interesting newsolution for good old AM/FM car radio that makes a lot of sense. Anewly developed dual-tuner receiver chipset uses sophisticated digitalsignal processing techniques to enable excellent reception qualitywhile reducing interference even in presence of challenging signalconditions such as weak field and strong multipath (reflection frommountains and buildings). The advanced digital receiver integratesaudio signal processing and Radio Data System (RDS) decoding, and hencedelivers quality and system cost optimization suitable for high-end carradios. The solution tunes to all current analog radio servicesworldwide (AM, FM and US Weather band) as well as to the recentlyintroduced digital broadcasts (Digital Audio Broadcasting, DigitalRadio Mondiale, HD radio), providing suitable interfaces to externaldecoders.
