Deconvolution　algorithm　is　a　very　good　method　to　do　the　signal　reconstruction　and　system　identification.　The　paper　researched　in　pulse　parameter　measurement,　by　using　of　the　deconvolution　algorithm　to　calculate　the　time-domain　characteristic　of　the　signal　source　and　the　broadband　sampling　oscilloscope.　The　principle　of　the　method　was　analyzed,　the　experiment　and　data　processing　were　done　by　the　method.　And　the　comparision　by　swept-sine　measurement　in　frequency-domain　was　also　done.　©2012　IEEE.
