Abstract
Some embodiments of the invention relate to a time measurement circuit for an incoming signal. In some embodiments, the time measurement circuit has a comparator stage, for generating a comparator output signal depending on a fulfillment of a criterion by the incoming signal, wherein exceeding or falling below a threshold value is defined as the criterion. Furthermore, a digitization stage is provided, for sampling, which is performed at a defined sampling rate, of an input signal fed to the digitization stage and converting it into digital data containing sampled values for the input signal, and an evaluation unit for determining a chronological location for the incoming signal by evaluating the digital data.
