Abstract
The present invention provides an apparatus and a method for checking the plausibility of an excitation signal. The apparatus is designed with: an input signal device () which is designed to provide an input signal () on the basis of the excitation signal (), the plausibility of which is to be checked; an amplitude estimation device () which is designed to determine an estimated amplitude value () for an amplitude of the excitation signal () on the basis of the input signal () provided; a phase angle estimation device () which is designed to determine an estimated phase angle value () for a phase angle of the excitation signal () on the basis of the input signal () provided; a diagnostic device () which is designed to generate a diagnostic signal () on the basis of at least the determined estimated amplitude value () and the determined estimated phase angle value (); and a plausibility-checking device () which is designed to check the plausibility of the excitation signal () on the basis of the diagnostic signal () depending on a predetermined range of values for the diagnostic signal ().
