We all at a point, have wondered what the root and backbone of the digital world. Almost all devices we
use daily make use of digital electronics in some capacity. Digital electronics is inarguably what has
made the digital world possible.
Digital electronics refers to circuits that use digital signals. These circuits represent information by the
use of binary numbers 1 and 0. 1 and 0 represent signals by discrete bands of analog levels. Digital
electronics are constructed using logic gates, each of which performs a different function. The circuit will
make use of various standard components, that are put together in different combinations to achieve
the desired results.
To fully grasp the concept of digital electronics knowledge in the following areas is critical: inverters,
AND gate, OR gate, NAND, NOR, Exclusive-OR, integrated circuits. Combinational Logic, truth tables,
Boolean algebra, the Karnaugh map, DeMorgan's theorem, the universal property of NAND gates.
Applications of combinational logic in decoders, encoders, multiplexers, demultiplexers, and parity
checkers. Integrated Circuit Technologies: L, CMOS circuits, emitter-coupled Logic (ECL), gallium
arsenide (GaAs), programmable logic devices (PLDs), field-programmable gate arrays (FPGAs),
Sequential Logic: latches and flip-flops, master-slave and edge-triggered devices, D-types, S-R types, and
J-K types. Synchronous Logic: counters, shift registers, the finite state machine (FSM), Implementation
with PLDs, and FPGAs. Memory and storage, Interfacing, and microprocessors.
Many of our household items make use of digital electronics. These include laptops, televisions, remote
controls, subwoofers, DVD players, to kitchen appliances like dishwashers and washing machines.
Computers are one of the most sophisticated examples and will make use of numerous, complex
circuits. There are possibly millions of pathways within the circuit, depending on how advanced the
computer and its functions are.
