Реферат: The invention relates to a method of estimating an intersection between at least two continuous signal representations (SR1, SR2) in a pulse width modulator,
at least one of said continuous signal representations (SR1, SR2) being non-linear,
said method comprising the step of providing an intersection estimate (CPE) between said at least two continuous signal representations on the basis of at least one iteration comprising at least one iterative call of a function describing said continuous signal representations (SR1, SR2) being non-linear and whereby said estimating of intersections are performed in a pulse width modulation modulator. According to an embodiment of the invention, a simple iterative call of the established continuous signal representation, e.g. an interpolation polynomial, will provide the desired intersection. It should be noted that the established estimate might be provided without any complicated root solving and avoiding division and even square root.
