What is electronics & telecommunication engineering?

It all starts with the smallest things. We electronics engineers call it an electronic switch. The rest of the world calls it a diode. It’s a strange thing. It behaves in two directions, a short circuit and an open circuit. They then tell you about its limitations. It was a two-leg problem. Now, it’s a three-leg thing that changed everything. It revolutionized the electronic industry. We electronics engineers call it a current-based amplifier. The world calls it a transistor. FET is a voltage controlled device. Hurrah! Finally, we found what we were looking for. It was developed into MOSFET. It’s quite amazing. Today, we can make a billion of these items in a 1 mm square area. It is in your smartphone, laptop, calculator, etc. It is everywhere, but you don’t feel it. It’s a switch, even though electronics engineers still believe it. It doesn’t have to be complicated.

As we were working on a MOSFET-related circuit, a guy began amplifying the signals. It’s not a bad thing. It’s OP-AMP. It can be used to design any analog circuit. It’s very easy to use.

But all the while we were working with analog signals, someone suggested that we call ON 1 and OFF 0. So, we started designing 1010 circuits. Although it is not an easy task, this is our favorite subject.

It gets more complicated, as they explain that there are many more types of signals. A laplace transform, which is the ability to analyze both input and output signals, can provide a lot more information about systems. *Sigh*, transforms. They were never my favorite. They started to appear in more and more subjects. Then, I had to learn. They were easy to learn, and I can now transform without using my left hand. They are everywhere. Even in the FM that you just listened too. That M in FM is modulation. It is what we need, so we made it. In this noisy world, we can also transmit 1 or 0. What is this noise? We don’t like the noise, but we must deal with it. It can affect our three-legged friends. If there is too much noise, A can become B. They tell us that it’s gaussian noise. As if we hadn’t been disturbed enough by the guy in XII.

Gauss’s law was established. Maxwell’s equations tell us how to send waves through air. We will then be able to develop earphones. This will allow us to guide waves and then release them in the air using a resistor. This resistor is called an antenna in the world. An antenna can come in many sizes and shapes.

Sometimes, we do things at our own signal so that no one can read it. The government is not immune. 😉

From developing a line-follower robot to creating a robot that can kill another robot with one command, we move on. To develop a wireless telemetry network, we start by studying antennas. Today we will be using diode to create a wireless telemetry system. We want to add upto 10 million MOSFETs per square meter. Electronics is the world we live in. It is a constant struggle to make the world better for our children and future generations.

You may be called a fool by your friends for learning so much. They will still say it’s cool when your robot takes apart another robot. We can now process 100 million instructions per second, even though some branches remain stuck on cantilevers by shear force.

This is the essence of electronic and digital communication.
