The Universal Gates Trainer NV6552 is an elite training system for the digital laboratories. It is useful in understanding the basic concepts and functioning of universal gates and their use as other logic gates. This trainer describes the formation of AND, OR, NOT, NAND, NOR, XOR and XNOR gates using NAND and NOR gates which are called universal gates. The training system is designed in such a way that for performing any experiment students have to connect the links by patch cords, so it is very helpful for students to learn step by step design of each gate using universal gates. Attractive input and output sections are provided on trainer in such a manner so that multiple experiments can be performed simultaneously.
