Digital Logic Design and Digital Electronics Course

Everything that works on batteries around you; and everything that can have a circuit board, is built by using principles of Digital electronics and Digital Logic design. Digital electronics deals with circuits that operate on digital inputs and outputs. In this course, we will begin by getting to the bottom of what it means to be digital. How digital values are manipulated by circuits. Eventually, we will progress to the memory aspect of digital electronics. We will understand the function of basic digital circuits like counters.

Course content

Digital Number Systems And Base Conversions

When we design digital systems, we frequently deal with number systems apart from binary. Let’s take a look at hexadecimal, decimal and octal number systems.

Boolean Algebra – All the Laws, Rules, Properties and Operations

Since binary is a language in its own way, it is governed by some laws. These laws fall under Boolean Algebra. These are simple rules that you need to follow to perform operations on binary data. A must for every digital electronics course.

Binary Arithmetic – All rules and operations

As the name implies, binary arithmetic deals with the rules governing the arithmetic operations on binary digits in the binary number system.

Sequential and Combinational logic circuits – Types of logic circuits

There are two main types of digital logic circuits in digital electronics. Combinational and sequential logic circuits are found in every digital device around you. Let’s take a look at what these digital circuits are and what they comprise.

Logic Gates using NAND and NOR universal gates

We kick off our digital electronics course with these essential digital components. The basic building blocks of the digital world are logic gates. They are used to implement Boolean logic which is the crux of all digital operations.

Half Adder, Full Adder, Half Subtractor & Full Subtractor

Arithmetic combinational circuits are the norm in modern ICs. In this post, we will take a look at adders and subtractors. These are the most basic yet important circuits that we will learn about in this digital electronics course.

Comparator – Designing 1-bit, 2-bit and 4-bit comparators using logic gates

A comparator is a combinational logic circuit that compares input bits and gives an output that indicates the equality/inequality of a digital circuit.

Multiplier – Designing of 2-bit and 3-bit binary multiplier circuits

To multiply binary digits we need a special digital circuit called a multiplier. Let’s understand some multiplication rules and design the third most important arithmetic logic circuit that we will study in this digital electronics course.

4-bit parallel adder and 4-bit parallel subtractor – designing & logic diagram

In digital electronics, if you have more than two or three bits of data to add or subtract, a full adder or a full subtractor won’t suffice. To add and subtract two four-bit numbers we use parallel adders and parallel subtractors.

Carry Look-Ahead Adder – Working, Circuit and Truth Table

Speed is always a major concern in any digital application. Addition is a very common digital operation. Carry look-ahead adders are great at fast additions.

Multiplexer and Demultiplexer – The ultimate guide

A multiplexer and a demultiplexer are two important combinational circuits important for digital data transmission. This is our one-stop guide for understanding digital multiplexer and demultiplexer circuit design, truth tables, cascading, working, applications and other FAQs.

Code Converters – Binary to Excess 3, Binary to Gray and Gray to Binary

It’s necessary to understand digital code converters to realize the importance of encoding data to fit our demands of designing logic circuits. Code converters are also an important class of digital electronics circuitry.

Priority Encoders, Encoders and Decoders – Simple explanation & designing

Digital data transmission, encryption, and compression are vital operations and are done by encoders and decoders. Let’s study their working and design.

Flip-Flops & Latches – Ultimate guide – Designing and truth tables

One of the most integral parts of modern digital electronics and gadgets is the memory. Storage is expensive. And flip-flops are the building blocks of storage.

Shift Registers – Parallel & Serial – PIPO, PISO, SISO, SIPO

In digital electronics, data needs to be moved quickly and efficiently. Shif registers are an excellent way of transporting digital data.

Counters – Synchronous, Asynchronous, up, down & Johnson ring counters

Counters perform the function of counting events in digital electronics and digital circuits. There are many types of digital counters. We will take a look at a few important ones and understand the process of designing them.

Parity Generator and Parity Checker

It’s necessary for digital signals to be error-free. Thus there must exist an error correction/detection mechanism. Using Parity bits is the easiest way.

Memories in Digital Electronics – Classification and Characteristics

The efficient storage of digital data is an evergreen field in the semiconductor digital memory industry. Let’s look at the different types of digital memories available for us to choose from.

Programmable Logic Devices – A summary of all types of PLDs

Now that you have a hang of what digital logic entails, you can understand PLDs. These devices can be ‘programmed’ to act a certain way and are the bread and butter of the modern computing world. Really interesting stuff.

Difference between TTL, CMOS, ECL and BiCMOS Logic Families

Logic families are an important aspect of designing digital ICs. Let’s take a look at the different options available to us and compare them based on their merits and demerits.
