摘要： In one embodiment, the present invention includes a method for determining if a frequency control instruction would cause a first capacitor bank to reach a limit and adjusting the first capacitor bank in a first direction using a calibration value and adjusting a second capacitor bank in a second direction if the first capacitor bank would reach the limit. Furthermore, the calibration value may be calculated and stored in accordance with other embodiments. In such manner, small changes in capacitance and correspondingly small changes in frequency may be effected.

摘要： Methods and systems are disclosed that mitigate stereo noise in FM broadcast receivers by assessing L−R (left-minus-right) and L+R (left-plus-right) levels within tuned FM channels. These assessments are used to facilitate control of a blend from stereo output signals to mono output signals in order to reduce and mitigate stereo noise and distortion in the audio outputs. The side effects of the disclosed systems and methods are unobtrusive as compared to prior blend-to-mono techniques.

摘要： 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.
