FIELD: physics; computer engineering. ^ SUBSTANCE: invention relates to devices for individual or group training for working with digital logic electronic circuits. The device contains the following: a magnetic demonstration board, modules whose housing is fitted with fastening magnetic strips with electrical circuit components and terminals attached to their faces, one of the modules is a light-emitting diode module and the second - a switch, a set of connecting leads, a power supply unit, a supply extension, a double switch module, a semiconductor module, modules with logic components made in form of NAND and NOR components, a module with "logical one" function, where on the face of each module there are schematic symbols of electrical circuit components, and the power leads are made with double conductors with a coaxial connector and a polar contact in the middle. The housing of each module is made in form of a box inside of which there are boards with microcircuits with outputs on terminals, where the boards are mounted using connection pipes on the inner surface of the base of the box which enable threaded fastening of the boards. On the inner surface of two opposite sides of the box there are recesses for attaching fastening magnetic strips and on the lateral side of the housing there are power sockets for the module. ^ EFFECT: design of a universal device for studying digital logic. ^ 2 cl, 13 dwg |
