Abstract
An automatic frequency control (AFC) system in an electronic device is operated by using an AFC-algorithm component to determine a frequency error corresponding to a difference between a frequency of a signal output from a signal generator and a received signal frequency. The frequency error determined by the AFC-algorithm component is multiplied by a scaling factor, which is set to zero after an adjustment has been made to change a frequency of the signal output from the signal generator. The scaling factor is increased from zero to one over time. The scaled frequency error is used to determine whether to adjust the frequency of the signal output from the signal generator.
