Abstract
The present disclosure pertains correcting linear interpolation errors. In one embodiment, a system comprises an input configured to receive the periodic signal at a first sampling rate and an output configured to provide an interpolated representation of the periodic signal at a second sampling rate. A linear interpolation subsystem may establish a ratio between the first sampling rate and the second sampling rate to determine a slip frequency. The linear interpolation subsystem creates an interpolated representation of the periodic signal based on the ratio. The interpolated representation of the periodic signal includes a deterministic error attributable to interpolation. A linear interpolation correction subsystem may correct the deterministic error attributable to the linear interpolation subsystem and create a corrected interpolated representation. An application interface subsystem may provide the corrected interpolated representation to an application.
