What are digital logic circuits?




Definition




Digital logic circuits are electronic devices that use binary signals (0 or 1) to perform logical operations (such as NOT, AND, OR) on input signals and produce output signals according to predefined rules. Digital logic circuits can be classified into two types: combinational and sequential.


Types of digital logic circuits




Combinational logic circuits are those that produce output signals only based on the current input signals. They do not have any memory or feedback elements. Examples of combinational logic circuits are adders, subtractors, comparators, multiplexers, decoders, etc.


Sequential logic circuits are those that produce output signals based on both the current and previous input signals. They have memory or feedback elements that store the state of the circuit. Examples of sequential logic circuits are flip-flops, registers, counters, shift registers, etc.


Basic logic gates




Basic logic gates are the building blocks of digital logic circuits. They are electronic devices that perform a single elementary logic operation on one or more input signals and produce one output signal. There are seven basic logic gates: NOT, AND, OR, NAND, NOR, XOR, and XNOR. Each logic gate has a symbol, a truth table, and a Boolean expression that describe its operation.


The NOT gate is a logic gate that performs the logical negation operation. It has one input and one output. The output is the opposite of the input. The symbol, truth table, and Boolean expression of the NOT gate are shown below.

Design methods




Designing digital logic circuits involves finding the optimal combination of logic gates that can perform a desired logical function on given input signals and produce output signals according to a specification. There are various methods for designing digital logic circuits, such as truth tables, Karnaugh maps, Boolean algebra, etc.


A truth table is a tabular representation of the input-output relationship of a logical function. It lists all possible combinations of input values and their corresponding output values. A truth table can be used to verify the correctness of a logic circuit or to derive a simplified Boolean expression for a logic function.


A Karnaugh map is a graphical representation of a truth table that can be used to simplify a logic function by minimizing the number of terms in its Boolean expression. It consists of a grid of cells that represent the minterms (product terms) or maxterms (sum terms) of a logic function. Adjacent cells in the grid differ by only one variable. By grouping adjacent cells that have the same output value, common variables can be eliminated and simplified expressions can be obtained.


Boolean algebra is a branch of mathematics that deals with the manipulation of binary values and logical operations. It can be used to simplify and optimize logic functions by applying various rules and laws, such as De Morgan's laws, distributive law, commutative law, associative law, etc.


Design examples




Let us see some examples of designing digital logic circuits using different methods.


Example 1: Design a half adder circuit using basic logic gates. A half adder is a combinational logic circuit that can add two one-bit binary numbers and produce a sum bit and a carry bit as outputs.


Solution: A half adder can be designed using an XOR gate and an AND gate. The truth table, Karnaugh map, Boolean expressions, and logic diagram of the half adder are shown below.

A full adder is a combinational logic circuit that can add three one-bit binary numbers (two operands and a carry-in) and produce a sum bit and a carry-out bit as outputs.


Solution: A full adder can be designed using two half adders and an OR gate. The truth table, Karnaugh map, Boolean expressions, and logic diagram of the full adder are shown below.

Digital systems




Digital logic circuits are used to design and implement various digital systems that perform specific functions on binary data. Some examples of digital systems are:


  • Arithmetic circuits: These are digital systems that can perform arithmetic operations, such as addition, subtraction, multiplication, division, etc. on binary numbers. For example, a ripple-carry adder is a digital system that can add two n-bit binary numbers using n full adders connected in series.



  • Multiplexers: These are digital systems that can select one of many input signals and forward it to the output. They are also known as data selectors. For example, a 4-to-1 multiplexer is a digital system that can select one of four input signals (A, B, C, D) based on two select signals (S0, S1) and forward it to the output (Y).



  • Decoders: These are digital systems that can convert a binary code into a one-hot code. They are also known as data distributors. For example, a 2-to-4 decoder is a digital system that can convert a 2-bit binary code (A1, A0) into a one-hot code (Y3, Y2, Y1, Y0) such that only one output is high for each input combination.



  • Registers: These are digital systems that can store and shift binary data. They consist of flip-flops connected in parallel or in series. For example, a parallel-in parallel-out register is a digital system that can store and transfer n-bit binary data using n flip-flops connected in parallel.



  • Counters: These are digital systems that can count the number of pulses or events in a given time interval. They consist of flip-flops connected in series or in feedback loops. For example, a synchronous up-counter is a digital system that can count up from 0 to 2-1 using n flip-flops connected in series with a common clock signal.



Computer architecture




Digital logic circuits are also used to implement computer architecture, which is the structure and organization of the components of a computer system. Some examples of computer architecture components are:


  • CPU: This is the central processing unit of a computer system that executes instructions and performs calculations and data processing. It consists of an arithmetic logic unit (ALU), a control unit (CU), and registers.



  • Memory: This is the component of a computer system that stores data and instructions for the CPU. It consists of random access memory (RAM), read-only memory (ROM), cache memory, etc.



  • ALU: This is the component of the CPU that performs arithmetic and logical operations on data. It consists of various arithmetic circuits, such as adders, subtractors, multipliers, dividers, etc.



  • CU: This is the component of the CPU that controls the operation and timing of the CPU and other components. It consists of various logic circuits, such as decoders, multiplexers, registers, counters, etc.



  • I/O: This is the component of a computer system that communicates with external devices, such as keyboards, monitors, printers, etc. It consists of various logic circuits, such as buffers, drivers, receivers, etc.
