INTRODUCTION TO THE DIGITAL ELECTRONICS

•What is “Electronics”?

“Electronics means study of flow of electrons in electrical circuits.”

• The word Electronics comes from electron mechanics which means learning the way how an electron behaves under different conditions of externally applied fields.

• The Institution of Radio Engineers has given a definition of electronics as "that field of science and engineering, which deals with electron devices and their utilization."

• Now, let’s first learn what is meant by the word “digital”.

WHAT IS DIGITAL?

CONT……..

• a communication channel or method? 

• A convenience enabler? 

• 1s & 0s? 

• The inverse of analog?

• Bits versus atoms?

• Something we can no longer live without?

• I am often asked ‘what is digital’? … ‘is it just our website, or broader than that?’ … ‘what exactly do you mean?’

So, I asked around to find out the word-on-the-street around ‘digital’.  I was impressed with how many different, nuanced, and insightful answers I was given on the definition — I had to put it all together into a video in order to capture the rich and diverse viewpoints.  In the video, you can learn what others think ‘digital’ is, as well as how we define it.

• Watch the video to see how our colleagues and members of the public describe it; listen to hear if your definition is included; and let me know whether you’d add a different perspective.

WHAT IS DIGITAL?

SOURCE: http://whatis.techtarget.com/definition/digital

• Formally, Digital describes electronic technology that generates, stores, and processes data in terms of two states: positive and non-positive. Positive is expressed or represented by the number 1 and non-positive by the number 0. Thus, data transmitted or stored with digital technology is expressed as a string of 0's and 1's. Each of these state digits is referred to as a bit (and a string of bits that a computer can address individually as a group is a byte).

WHAT IS DIGITAL ELECTRONICS?

• Let’s now define “Digital Electronics”.

“Digital electronics, or digital (electronic) circuits, represent signals by discrete bands of analog levels, rather than by a continuous range.”

• So, now let’s find out what is meant by “analog”?

WHAT IS ANALOG?

• Analog means continuous in nature, such my voice, or any of the bioelectric signals generated by a living things.

• Digital means, as defined earlier, discrete, e.g., temperature recorded everyday in the morning at 8:00 a.m.
