1. A method for sampling a pulse signal, the method comprising:
collecting, by a device, a plurality of first sampling points on a rising edge portion of the pulse signal according to a plurality of preset sampling thresholds, wherein each sampling point of the plurality of first sampling points is represented by one of the preset sampling thresholds and a first time corresponding to the one of the preset sampling thresholds;
collecting, by the device, a plurality of second sampling points on a falling edge portion of the pulse signal according to the plurality of preset sampling thresholds, wherein each sampling point of the plurality of second sampling points is represented by one of the preset sampling thresholds and a second time corresponding to the one of the preset sampling thresholds; and
collecting, by the device, a third sampling point of the pulse signal at a third time separated from the first time or the second time by a preset time interval, wherein the third sampling point is represented by the third time and a response amplitude corresponding to the third time.
