This package includes a number of methods of determining the delay between two period signals. The delay may be calculated to subsample accuracy. Methods include: three-point interpolation using parabolic, Gaussian, or cosine functions; a phase method; and an iterative method.
A simple example is included, as well as a more comprehensive example demonstrating the comparative performance of the methods under various signal properties.
