Design and Implementation of Asynchronous Sexagesimal Counter
[Purposes]In the teaching of digital electronic technology,the design of integrated counter is the focus and difficulty of teaching.In order to make students complete the counter design quickly and accurately,this paper uses the integrated counter 74LS161D to design the sexagesimal asynchronous plus counter.[Methods]Using the design method of feedback preset method and combinational logic cir-cuit method,First,the asynchronous sexagesimal circuit diagram is obtained according to the sequential circuit design step,and then the Multisim10.0 software platform is used to simulate,Record and analyze the operating results in accordance with the design requirements;Finally,physical experimental analysis was conducted on the digital electronic technology experimental platform in the laboratory to further verify the stability,correctness,and reliability of the design in practical operation.[Findings]The experi-mental results show that the designed sexagesimal counter circuit meets the design requirements.[Con-clusions]The simulation analysis and circuit design are carried out by Multisim10.0,which ensures the smooth progress of the physical experiment,improves the design efficiency,reduces the probability of failure,strengthens the students' understanding of the design process,and stimulates the students'inter-est in designing the counter.
