Abstract: A signal interpolation method is described. The method includes: receiving an analog input signal; digitizing the analog input signal received, thereby obtaining a digitized input signal having samples; determining a crossing of the digitized input signal with respect to a threshold that was set; and interpolating a signal between at least two successive samples, wherein the signal interpolated has two signal portions each having a linear slope, and wherein one of the signal portions crosses the threshold. A measurement instrument is also described.

Abstract: A trigger method for triggering a measurement device on a signal pattern in a signal is provided. The trigger method comprises the steps of receiving the signal pattern, receiving the signal, computing a first cross-correlation of the signal pattern and the signal, and triggering the measuring device, based upon the first cross-correlation.

Abstract: A signal processing method is described. The signal processing method comprises the following steps: An input signal is received. The input signal is processed from a start point to a preliminary stop point based on at least one first processing parameter, thereby obtaining a first processed signal. The at least one first processing parameter is adapted based on the first processed signal, thereby obtaining at least one second processing parameter. The input signal is processed from the preliminary stop point to the start point based on the at least one second processing parameter, thereby obtaining a second processed signal. At least one output parameter is generated and/or an output signal is synchronized with the input signal based on the second processed signal. Further, a signal analysis module is described.
