Intelligence Electrical Devices and Digital Electrical Circuits

With each passing day, our world is becoming more digital and more integrated. The word 'digital' is now a part of our everyday life with items such as digital cameras, digital weighing machines, digital signatures, digital watches, digital payments, digital art and much more. What does 'digital' mean? In the Cambridge dictionary, it is defined as ‘recording or storing information as a series of the numbers 1 and 0 to show that a signal is present or absent’. The digital world is represented in binary numbers that have only two values: 0 and 1 representing "off" and "on" or  "low" and "high" or that a signal is ‘absent’ or ‘present’. This free online electronics tutorial on digital circuits will first introduce you to binary systems which include binary numbers and binary arithmetic. You will also learn how to distinguish and compare the binary system with the decimal system that is generally used in everyday maths. This part of the electronics course will also give you insight into how the decimal numbers are converted into binary codes and how they are used by computers and digital devices to send, receive, and store data.

A digital circuit comprises various components of which the logic gates are the primary building blocks. These gates combine in different ways to form digital circuits that are associated with different functionalities and represented as binary bits. With this free online electronics course, you will gain an understanding of the three different categories of logic gates: the basic (AND, OR, NOT), universal (NAND and NOR) and special (EX-OR and EX-NOR) gates. You will also be introduced to the negative AND and OR gates and the particular function of each gate as represented with the help of a truth table. Thereafter, you will learn how the different combinations of these gates form complex digital circuits including studying the two types of digital circuits: sequential logic and combinational logic, which are part of the digital appliances we use every day.

Digital electronics are very important in today’s life as we are increasingly relying on computers to improve our modern lives. At the end of this electronics training you will be able to analyze the different kinds of combinatorial and sequential digital systems that are present in computers, mobile phones, calculators, digital watches and much more. This course will teach you the fundamentals of electronics and is aimed at developing an understanding of digital electronic circuits and prepares anyone interested in learning digital electronics or students who wish to pursue a professional career in intelligent electronic devices. If you aspire to play a leading role in the progress of technology by developing flexible, low-cost, and dependable digital devices, then bring your basic understanding of electrical circuitry and ability to read electrical circuit diagrams and enrol for this exciting, easy-to-understand basic electronics course. Embark on your journey into the digital realm and start solving real-world problems that add value to this modern electronics and digital era.
