Abstract:In order to achieve a method in logistic function processing based on computer software, the paper discussed the principle and feasibility of using a VIdecoder as scanning logical operation unit to processing multiinput&outpt logistic function, and designed the application system based on LabVIEW, experiment shows that the system has the characteristic of independence on the number of variables and functions,universal and easeofuse,can be connected for data communication, and used in domain of simulation and actual measurement.
