"Digital electronics is a field of electronics involving the study of digital signals and the engineering of devices that use or produce them."
The study of digital circuits and their basic components, including logic gates, boolean algebra, and combinational and sequential circuits.
Boolean Algebra: A fundamental concept in digital logic, it deals with the mathematical operations and properties of logic gates and their symbols.
Logic Gates: The building blocks of digital circuits that perform logical operations, such as AND, OR and NOT.
Truth Tables: A table used to represent the boolean expressions of the logic gates, and their corresponding outputs.
Karnaugh Map: A method of simplifying boolean expressions by grouping adjacent 1's in a table.
Combinational Circuits: Circuits that combine different logic gates in order to produce a specific output based on the input.
Sequential Circuits: Circuits that use feedback to store information from past inputs and produce an output based on both past and current inputs.
Flip-flops: A basic component in sequential circuits, it is a latch that can store one bit of information.
Registers: A group of flip-flops that can store multiple bits of information.
Counters: A sequential circuit that counts the number of clock pulses it receives, and can be used for various applications such as frequency division or time measurement.
Multiplexers and Demultiplexers: A multiplexer selects one of several input lines and steers it to a single output line, while a demultiplexer performs the opposite function.
Adders and Subtractors: Circuits that perform binary addition and subtraction, which are used in digital arithmetic.
Digital-to-Analog and Analog-to-Digital Converters: Circuits that convert digital signals to analog signals (or vice versa), which are used in many electronic devices, such as audio players and computers.
Memory Elements: Circuits that can store digital data for later use, which are used in many electronic devices, such as computers and mobile phones.
Boolean Function Minimization: A method of simplifying complex boolean functions to reduce circuit complexity and improve speed and efficiency.
VHDL and Verilog: Design languages used to describe and simulate digital circuits.
AND gate: A logic gate that produces a high output only if all of its inputs are high.
OR gate: A logic gate that produces a high output if any of its inputs are high.
NOT gate: A logic gate that produces a high output if its input is low, and vice versa.
XOR gate: A logic gate that produces a high output if its inputs are different, and a low output if they are the same.
NAND gate: A logic gate that produces a low output only if all of its inputs are high.
NOR gate: A logic gate that produces a low output if any of its inputs are high.
XNOR gate: A logic gate that produces a low output if its inputs are different, and a high output if they are the same.
Binary adder: A digital circuit that performs the addition of two binary numbers.
Multiplexer: A digital circuit that selects one of several inputs and forwards the selected input to a single output.
Demultiplexer: A digital circuit that receives a single input and forwards it to one of several outputs.
Decoder: A digital circuit that converts a binary code into a set of outputs.
Encoder: A digital circuit that converts a set of inputs into a binary code.
Flip-flop: A digital circuit that stores a single bit of information.
Counter: A digital circuit that counts the number of clock cycles and produces an output based on the count.
Shift register: A digital circuit that stores and shifts a binary value.
Comparator: A digital circuit that compares two binary values and produces an output based on their relationship.
Arithmetic logic unit (ALU): A digital circuit that performs arithmetic and logical operations on binary numbers.
Memory: A digital circuit that stores binary information.
Programmable logic device (PLD): A digital circuit that can be programmed to perform a specific function.
Field-programmable gate array (FPGA): A digital circuit that can be reprogrammed for different applications.
