摘要： A control unit supplies a new control value to a frequency source. The value is determined by the frequency source frequency and the reference frequency. The control unit further calculates a rate of change value based at least on the new and a previous control value if there is communication with the reference frequency generator and stores these values in corresponding stores. Another control unit calculates a new control value based on the rate of change value from the rate of change store and the last used control value from the control value store and supplies the new control value to the frequency source if there is no communication with the reference generator.

摘要： A tuning arrangement in a radio receiver includes a front-end circuit having a tunable band-pass filter that is capable of tunably selecting channels within at least one frequency band of an RF signal. A noise source coupled to an input of the tunable band-pass filter introduces a wide-band noise signal into the front-end circuit. A signal detector coupled to an output of the front-end circuit measures at least one signal power associated with a filtered noise signal derived from the wide-band noise signal. A tuning controller, coupled to the tunable band-pass filter by a tuning control signal, adjusts the tuning control signal in response to the at least one measured signal power for tuning the tunable band-pass filter to a desired filter response.
