The application of LabVIEW in the digital logic experiment

According to the features of the LabVIEW, this article simulate the experiment of digital logic. Taking the MM74HC138 3-to-8 Line decoder and the 7448 BCD-to-7-segment decoder for example, this article explained the application of LabVIEW in digital logic experimental teaching, and completed design of the assembly logic circuit output system and extinguished zero function of 12 digital display system, and displayed the result by digital display. The actual experimental results verify the correctness of the simulation system, enrich the digital logic experiment teaching method and means, and enhance the students' learning interest and enthusiasm.
