Abstract :
The new methods of harmonic signal frequency adjustment are proposed and investigated. They are based on algorithms of instantaneous frequency and phase estimations. The algorithm of frequency estimation is synthesized using the second-order auto regression model of sine wave. The algorithm of phase estimation is based on maximum likelihood function method. Instantaneous frequency estimation allows to improve adjustment speed and work range.
