Abstract
Embodiments of the invention describe a method and a device for digital measurement of the momentary frequency response of the phase-path component of a modulator, based on digitally sampling the output frequency of the modulator by clocks and count values derived from components already used by the modulator, e.g. a counter in a divider, and a reference frequency based on a crystal oscillator.
