These labs have built in DC Power Supplies, Pulse Generator, Pulser Switches, Data Switches, Logic Probe, Digital Display, TTL/CMOS Mode Selector, and LED Display. The boards can be used as standalone unit with external DC Power Supply and logic data switches, or can be used with Scientech Digital Labs Scientech 2611/Scientech 2614. Operation of Full adder: Table.1 show the truth table for the full adder with three inputs A, B, and C as a carry in. Test points are provided to observe the waveforms/ signals and to measure voltages at different nodes. A basic explanation of whats going on: In truth tables, the rows alternate 1 or 0 every 2 n number of rows, where n is the the number of columns that the given column is away from the rightmost column. Logic diagrams on the boards provide easy understating of the concepts. The boards are very user friendly and support self learning through flexibility of making circuit connections. IC 7483 is a 4 bit parallel adder which consists of four interconnected full adders along with the look ahead carry circuit. Scientech Digital Electronics Experiment Boards are designed as a comprehensive Modular solution for beginners to explore the fundamentals of a variety of basic building blocks in Digital Electronics.
