F1-4

CLASSICAL DIGITAL CIRCUIT TRAINING SYSTEM

Objects
The training systems of electronic circuits are designed for educational practice.

All components are separated as in transparent plastic boxes with magnetic stand on a

grid panel or without magnetic on a rubber matrix. Circuit assemble is made by leads

plug. The training systems are used in some certain experiments, it can be completed

according to the written experiment manual and also you can design other more

experiments with yourself.


Feature

The training system is used in the digital electronic circuits, it can be completed according to

the F1-4 experiment manual. Totally 57 recommend classical digital circuit experiments are

contained in this system with the corresponding components and more experiments can be

designed to do by yourself
