Abstract: A method performed by a receiver is provided. The method includes generating an RDS/RBDS candidate codeword from a set of RDS/RBDS symbols where the RDS/RBDS candidate codeword has a subset of RDS/RBDS values that differs from corresponding subsets of RDS/RBDS values in all other possible RDS/RBDS codewords and determining whether the RDS/RBDS candidate codeword meets an acceptance criterion by comparing a first subset of reliability values determined from the set of RDS/RBDS symbols and having signs that differ from corresponding signs in the subset of RDS/RBDS values with a second subset of reliability values determined from the set of RDS/RBDS symbols and mutually exclusive with the first subset of the reliability values. A first number of values in the first and the second subsets of reliability values is less than a second number of values in the RDS/RBDS candidate codeword.

Abstract: A technique includes digitally generating orthogonal modulated signals, each of which has spectral energy that is generally centered at an intermediate frequency. The orthogonal modulated signals are frequency translated to produce translated signals, each of which has spectral energy that is generally centered about a second frequency that is higher than the intermediate frequency. The translated signals are combined to generate a modulated signal.

Abstract: A magnetically differential input circuit (20) is arranged to define at least two loops (L1 and L2), wherein each of the loops traverses the input (231) of a receiving circuit. The loops (L1 and L2) are physically arranged so that a source of interference (L3) induces opposing signals in the loops (L1 and L2), thereby effecting cancellation of the interference at the input (231) of the receiving circuit. In one embodiment, the input circuit (20) is arranged to be electrically differential as well as magnetically differential.

Abstract: The integrated system on a chip with LINBUS network communication capabilities includes processing circuitry for performing predefined digital processing functionalities on the chip. A free running clock circuit generates a temperature compensated clock that does not require a synch signal from external to the chip. A LINBUS network communications interface digitally communicates with off-chip LINBUS devices. Communication between said on-chip LINBUS communications interface and the off-chip LINBUS devices is affected without clock recovery. The LINBUS network communication interface has a time base derived from the temperature compensated clock which is independent of any timing information in the input data received during a receive operation. The temperature compensated clock further provides an on-chip time reference for both the processing circuitry and the LINBUS network communications interface.
