The present disclosure provides a method for analyzing a signal, the method comprising receiving an incoming square-wave-like signal that comprises a predetermined frequency and a variable duty cycle, continuously forming the first derivative of the incoming square-wave-like signal, and determining at least one of the frequency, and the duty cycle of the received signal based on the first derivative. Further, the present disclosure provides a measurement application device.
