the Benefits of a Digital Circuit Design? 2

Modernization over Time:
Even though this technology was being worked upon since the early 60s and continued well into the 70s, their practical importance grew recently and most digital logic functions such as multiplexers, adders, comparators, decoders etc are based on TTL. Thousands of gates were able to be fitted to a single chip within the late 80s, through which, various PLDs or Programmable Logic Devices were formed.

PLDs use an array consisting of large numbers with AND, NOT and OR gates being arranged in a single design type, connected in a predefined manner. The 1980s saw huge developments being made to this field and a completely new architecture was added during this time frame. This structure used RAM based lookup tables instead of the conventional AND, NOT and OR logic. This device was known as FPAGs or Field Programmable Gate Arrays.

Current Methods of Circuit Designing:
Its basic layout was an array of CLBs or Configurable Logic Blocks, surrounded by an array of Input Output blocks. DCMs or Digital Clock Manager is best suited to diminish the effects of clock distribution delay, which is used to either increase or decrease a clock’s frequency. Drawing logic diagrams is the actual way of designing digital circuits that contain MSI or SSI logic functions.

At a Glance:
With the addition of LSI and VLSI logic circuits however, this process began to pose unforeseen problems. It was practically impossible to draw a structure consisting of Millions of transistors. This led to the evolution of Computer Aided equipments that could reduce human effort. This is how digital circuits are designed today. Many of the other designing techniques that were important during the age of TTL chips have also been out of commission for a very long time.

the Benefits of a Digital Circuit Design?

Integrated circuits were first introduced during the 60s and some of these early creations used as little as 100 transistors only in their complete design. These were known as SSI or Small Scale Integrated circuits and MSI or Medium Scale Integrated circuits. However, during the 90s a major transformation came around and LSI or Large Scale Integrated circuits were formed. These housed a few thousand transistors and quickly gained prominence in mass usage.

What are the Different Types of Circuits Used in a Transistor?
VLSI or Very large Scale Integrated circuits were used around the globe during the early 2000s and they house as many as 100,000 transistors for greater benefit. This arrangement was modified over a course of time and the current Digital Circuits we use consist of nearly 1,000,000,000 transistors. Now the primary question is how can an engineer work on a circuit that consists of a few Million transistors?

You should quickly draw your attention to the fact that all modern digital circuits are based on the three Logic Gates, namely AND, NOT and OR. Digital circuits can also be formed using NAND and NOR Logic Gates, each of which contain a maximum of four transistors. Hence, upon classifying Logic Gates, their functionality increases. Various technologies have been developed since the 90s and have been in use and one such example is TTL or Transistor-Transistor Logic.

How the capacitor and the resistor work – their relationship 2

To be continued from the  previous post.

How do the capacitor and the resistor work along with each other?

The capacitor and the resistor are the two most important, two widely used and the two basic elements or rather components that any electronic device would probably have. There is a certain way through which both of these elements perform together and come up with the desired result.

• As stated above, the capacitor is a store of energy. The reason behind this is interesting. Definitely it is not some sort of a vessel or a bowl in which energy can stay stored. As there are two plates that form the capacitor and there is a space in between these two plates, when electric current flows through the plates, the current or rather to be more specific, the electrons cannot pass that gap and stays stored in between.

 

• With the increase in the voltage this storage increases.

• Now with the resistor in that electronic device, the electron flow gets restricted. With a larger resistor, the resistance would be more and with a small resistor, the resistance would be less.

• Thus the stored electrons or the sored energy in between the capacitors would be converted to another form of energy. And thus we get the bulbs and the tubes in the homes and on the streets are illuminated.

How the capacitor and the resistor work – their relationship

The capacitor and the resistor are the two basic components that are required for the electronic circuit which can provide current to the electronic devices so that they run and work. When an electronic device performs, it is run by the electric flow – this is the simple theory that is known to everyone. However, the entire process is a matter of electron flow and involves a detailed technique.

What is a capacitor?

CAP
To simply describe what a capacitor is, it must be stated that a capacitor is a component, which essentially an electronic one and stores electric charge. This electronic component is made up of two plates that are also known as conductors and a dielectric material separates these two plates. The two plates or the conductors of the capacitor accumulate electric charge when it is connected to an electronic source. Thus, one plate holds a positive charge and the other plate holds a negative charge.

What is a resistor?

A resistor on the other hand is, as the name suggests, a resistor of the electricity flow. When the electricity flows through the capacitor or rather the electronic device, the resistor’s task is to resist or stop the electricity from flowing down. This task of resisting the electricity is known as the resistance and as the electricity faces resistance, it gets transformed into different forms to get released from this resistance. Thus, when electricity is passed through an electric bulb and gets resisted by the resistor, it gets released in an entirely different form of energy – that is, it gets transformed from electric energy to light energy and heat energy. Thus we see the bulb become illuminated.

its importance and benefits – an intro to the computer industry 2

Whether you run a business or a bank or even a huge industry, you will need the assistance of the computers. The reason is that the computer is the only device that can keep the records of the work, can recognize the difficulties with the work, and come up with solutions for those problems. Even when you depend on computers, you do not have to depend on human beings. This increases the accuracy of the work and decreases the involvement of time.

Although the invention of the computers dates back to the mid-19th century when Charles Babbage invented a giant machine that could calculate large integers, the modern computers have gone far beyond that and have become almost interactive. So, now when you come up with a problem, the computer will instantly offer you a solution.

What are the benefits of the computer industry?
Previously, industries had to stay dependent on the man powers. If there was any shortage of the supply with the human resources or if the quality of the workers were not up to the mark, the business had to suffer a lot. But with the discovery of the computers and the availability of the computer industry has made the businesses reach such a height that could only be dreamed of.

• Computers can keep a track record of the raw materials that are used, the stocks of the materials, and also a detailed record of the manufactured goods in your business. Even if there is anything confidential that has a risk of being stolen, like the formulas that are used in the business, then the computers can perform the task of a locker.

• The computer industry itself is a huge industry that involves too many engineers and runs a huge industry providing a good degree of opportunity for work.

• There is no doubt that computer industry can reduce the human labor and increase the accuracy of the task.

Which industries depend on the computer industry?
There is no one industry that does not need the assistance of the computers. From education to infrastructure, from construction to business, computer industry has a huge work area that cannot be run without computers.
