20110076972 | Systems and methods for tuning a broadcast radio receiver with digital display - Systems and methods that employ receiver circuitry to provide frequency display signals to a digital display without the presence or use of any external timing reference. One or more properties of a controllable local oscillator of a receiver circuit may be heavily or extensively characterized by measuring the local oscillator frequency under a variety of temperature and process conditions, and minimum to maximum frequencies. Measured local oscillator characterization information may be stored in memory, and may be accessed and used during normal operation to control the controllable local oscillator to produce a desired oscillator frequency for tuning the receiver circuitry to a desired radio frequency and for producing digital frequency display signals that are representative of the tuned radio frequency. | 03-31-2011 |
