Digital Electronic Trainer

Intended for elementary as well as advanced training in digital electronics. The trainer covers regular digital circuits by solderless interconnections through the use of 2 mm brass terminations and patch cords. Various clock generators, logic level input/output indicators and DC-regulated power supply are in build. The unit is housed in a finished wooden box enclosure with provision for the safe keeping of mains cord, patch cords and top lid for protection during storage.

The Trainer covers the Following Experiment :

01. Study of basic gates and verification of their truth tables:

1.1 NOT 1.2 OR 1.3 AND 1.4 NOR
