The object of the present invention is a device for measuring periodic oscillatory signal parameters comprising a sigmatata modulator and a zero crossing detector. Another object of the present invention is a method for measuring periodic oscillatory signal parameters by means of said device comprising the steps of: a) introduction into the sigma-delta modulator and the zero crossing detector of the periodic oscillatory signal whose parameters are to be measured. b) coding of said signal in the sigma-delta modulator in pulses of ones and zeros and generation of a synchronization signal by means of the zero crossing detector. c) synchronized processing of the signals obtained in the previous stage by means of digital processing circuits. The invention is applicable in the field of analog and mixed integrated circuits, and more specifically, with the evaluation and testing of analog signals by extracting oscillatory parameters using digital techniques.
