1.1.1. Need for Analog Designers

So, the need of analog designer of course, it will be there. So, if you see the fate of this analog electronics it is if it is in particularly in digital era. So, whenever we say the digital era, basically we are saying we do have more and more digitization with progress of time; but then it also has more and more application.

Despite the growing prominence of digital technologies, the significance of analog designers remains strong. In our digital era, characterized by increasing digitization, we are not just witnessing a rise in digital applications but also a concurrent need for analog components. This indicates that while digital systems may dominate, they still rely on analog systems to function optimally.

Think of a digital camera. It captures images as digital data, but the sensor that initially detects light is an analog device. Without this analog component, no digital image could be created.

But then, as I said that along with the digital core the requirement of this analog shell it will be remaining there; and hence the requirement of analog circuits it will be remaining.

This statement emphasizes the synergy between analog and digital systems. While digital technology often takes center stage, the necessity for analog circuits—referred to here as the 'analog shell'—continues to persist. As digital systems are built, they need analog circuits to interface with the real world, ensuring smooth operation and data acquisition.

Consider a smartphone. The touchscreen (digital) may command the interface, but the microphones and speakers (analog) are needed for sound, showing how both components are essential for the device to function effectively.

Of course, you need to be careful while this core portion it is; core portion it is dominating in terms of volume. The nature or the format of this analog shell it may evolve while it needs to be integrated.

As digital technology continues to advance, the structure and design of analog circuits (the 'analog shell') must also evolve to accommodate these changes. This highlights the importance of integration, requiring designers to be attentive to how these analog circuits adapt and work in alignment with their digital counterparts.

Think about how audio equipment has changed. Older systems had separate components (analog) for different functions, while modern audio systems often integrate these functions into a digital framework, requiring designers who can make sure everything works harmoniously together.

To summarize, so before we summarize; so in this context I must say that, what are the; what are the things we are going to covered in this analog electronics, to be more precise what may be the emphasis of this course. We will start with analog building blocks, their working principle, analysis and design and those building blocks.

The course on analog electronics will begin with a focus on analog building blocks. This involves understanding their working principles, how to analyze them, and how to design them effectively. This foundational knowledge is critical for anyone looking to get into analog design, setting the stage for more complex topics that will follow.

Imagine learning to build a house. You start with understanding the basic materials (bricks, wood) before you can build a sturdy structure. Similarly, in analog electronics, we start with understanding building blocks before assembling complex circuits.

So, here we will start with building blocks, different building blocks individually and then we will move to whatever the challenges we will face while we will be interfacing different blocks together to make a bigger system.

Once students grasp the individual building blocks, the next challenge they will face is interfacing these blocks. Each block has its unique properties, and merging them into a complex system poses various challenges that need to be understood for effective design.

Think of connecting multiple musical instruments in a band. Each instrument has its sound and way of playing, and to create a harmonious song, musicians need to understand how to blend their sounds seamlessly. Similarly, in circuit design, understanding how individual components interact is crucial.

And then we will see that how this interface effects are making it more and more challenging. And then we will make this circuit more towards practical analog modules.

As students work on applying their knowledge to practical analog modules, they will encounter real-world challenges related to interfaces. This will require problem-solving skills to ensure that all components work together effectively under practical conditions.

When culinary chefs create new dishes, they must consider how the flavors of individual ingredients affect the overall flavor of the dish. Designing circuits likewise requires considering how various components interact in real-world scenarios.

So, I should say we will start from this block level, namely bottom and then we will try to see what will be the interface effects. And then we will see that how we can make bigger system and then we will go from top to bottom; we will start from system level and then we will go to the implementation of the smaller level.

The learning process will have two perspectives: starting from the bottom (individual blocks) to understand integration challenges and then moving from the top (system level) to design smaller components effectively. This dual approach ensures comprehensive understanding and practical application.

Think of a city planning process. Planners first design the overall city layout (system level) and then break it down into individual buildings or sections (block level) to ensure everything fits well and serves its purpose effectively.

Now, moving to the conclusion; so what we have done is that, at least we got some idea about what is electronic circuits and what is the typical electronic system consists of and then also we have we got a sense of what may be the fate of analog electronic circuits, particularly in the digital era which is more and more getting dominated.

Concluding this segment, it's important to reflect on what has been covered: an introduction to electronic circuits, the components of typical electronic systems, and the relevance of analog circuits in our increasingly digital world. Understanding these relationships is vital for any aspiring designer.

Reflecting on the importance of analog circuits in a digital world is like recognizing the roots of a tree. While the tree grows tall and strong (digital progress), it still needs its roots (analog circuits) for stability and nourishment.
