Problems solved by technology

[0004] The present invention solves the problem that the existing experimental boxes used in the existing digital electronic technology experiment courses are seriously aging, and mainly use IC sockets and slots, which are easy to damage digital chips, require frequent maintenance, have many hidden troubles, and are available for use. There are few alternative analog devices, and it is difficult to better meet the requirements of digital circuit experiment teaching. The present situation provides a compact structure, intuitive use, easy maintenance, long service life, more stable and reliable use, and can meet the needs of modern digital circuits. Digital circuit experiment box required by circuit experiment teaching and its application method

Abstract

A digital circuit experiment box and a using experiment method are disclosed. The experiment box has a test box panel, a built-in power supply, a variety of signal sources, a logic indicating circuitboard and a digital display circuit board, and a plurality of experimental digital display tables. The experiment box panel is provided with a logic level indication area, a digital display area, a clock signal indication area, a trigger signal insertion area, a digital circuit chip solder connection area, a plurality of analog devices, and component plugs for expansion.. A logic level indicationarea is connected with an editing indication circuit board, a digital display area and a digital display circuit board are connected with each other, and that logic level indication area and the digital display area display the experimental state of the indication circuit. A digital circuit chip, a spare IC slot board, a plurality of analog devices and a component plug-in column are mounted on thefront face of the experiment box panel for improving the cognitive judgment and recognition ability of the students in the experiment teaching. The box has a compact structure, is easy to use and easy to maintain, and is long in service life, stable and reliable.

Description

technical field [0001] The invention relates to a teaching experiment box, in particular to a digital circuit experiment box and a use experiment method. Background technique [0002] The course "Digital Electronic Technology" is a basic course for majors such as electronic information engineering, electronic science and technology, and "Digital Electronic Technology Experiment" (that is, the digital circuit part of "Electronic Experiment") is a practice that matches the course "Digital Electronic Technology" Teaching is also a necessary teaching method to consolidate students' theoretical knowledge of digital circuits. It plays an essential role in promoting students' understanding of theoretical knowledge, mastering digital circuit experimental techniques, and training digital circuit innovation capabilities. [0003] However, the existing experimental box of the digital electronic technology experiment course has been used for teaching for 10 years and is seriously aging....
