Abstract
In accordance with described exemplary embodiments, correction is inserted into the feedback loop of a second order resonator used at the time of frequency transition. The correction is based upon parameters generated from a desired output signal frequency and a desired sampling frequency. The correction is generated to maintain i) constant amplitude, ii) continuous phase, and iii) the same sampling frequency during the frequency transition.
