摘要
A technique for determining the characteristics of an oscillatory test signal includes acquiring a plurality of consecutive samples of a test signal. The samples are mathematically fit to a sinusoidal model, which specifies a plurality of equations. The equations have unknowns that represent characteristics of a sinusoid that substantially intersects the plurality of samples. Solving the equations for the unknowns reveals the test signal's short-term characteristics.
