First, the linear theories of frequency stability in nearly sinusoidal feedback oseil-lators are simply reviewed. Then, the describing function method and determining equation approach are applied to obtain new expressions for the oscillation-frequency and the oscillation-amplitude stability of nonlinear nearly sinusoidal feedback oscillators. Finally, the differences of the expressions of oscillation-frequency stability derived from describing function method and determining equation approach are presented, and the relationship between descri-
bing function method and determining equation approach is studied.
