Quick Answer
Digital Electronic Experiments are panel trainers for digital logic and computer-principles practicals: logic gates and De Morgan theorems, adders and subtractors, counters and code converters, flip-flops, shift registers and RAM, multiplexers, A/D and D/A converters, and breadboard trainers. Typical boards have SPDT logic switches, LED output indicators and the circuit diagram printed on the panel, with a 1 Hz clock on the counter and flip-flop trainers. JLab currently offers 36 items in this category.
