ABSTRACT:
Method and apparatus for first converting energy pulses, such as from the energy-dispersive detector of an emission spectroscopy system, into multiple ramp signals, the ramps of which are parallel with the vertical distance between the ramps being proportional to energy pulse height. Digital samples of the ramps are taken and, from the known slope of the ramps, the vertical distance or difference may be determined using a least-squares algorithm. This value is the absolute amplitude pulse value.
