title: [A computerized analysis of phrenic nerve discharge signal].
abstract: The authors offered a method of computerized analysis to solve the problems met in the manual measurement of the signal of phrenic nerve discharge (PND). An envelope was gained via digital fullwave rectification and filter from the acquired PND signal. From it, some important parameters were measured automatically. The program ran well in animal experiments. The values of the PND parameters obtained by computer showed no significant difference as compared with the averaged values measured manually by researchers.
