Abstract
The method and device of the present invention is for synchronizing periodic signals. The method is comprised of the steps of obtaining input signals to be synchronized, delineating a plurality of terrain biased, dynamic threshold points, detecting the time at whcih each threshold point was attained by each input signal, averaging the times to determine a mean alignment time and aligning all signals with respect to the mean alignment time. The device of the present invention is comprised of an input system for receiving and converting an analog signal to a digital signal or signals; a microprocessor connected to the input system and having a control section for processing the signal in accordance with the method of the invention; and an output system connected to the microprocessor for sending the synchronized signal.
