Think About Communication Devices & How They Are Changing

It really wasn’t too long ago that cellphones became mainstream. Sure, car phones were around in the 70’s and 80’s and cellphones were with people in the 90’s, but it was in the 21st century when they became mainstream. Just shy of 16 years into the 21st century, and communication devices have evolved much more than just the introduction of cellphones.

1430115528uwqe6As a matter of fact, people don’t talk nearly as much on their phones anymore. They text, use social media and use apps for communication, and they also use devices aside from their cellphones, such as tablets and laptops. Video chat is increasingly popular, and it’s truly changing the way people wish to communicate.

It’s really interesting to me because I gave up my cellphone a couple years ago, and it has made me communicate in a way that is outside the norm. I work from my laptop, and while I don’t use a cellphone, I text and make calls from my laptop. There are plenty of websites that cater to this without charging you a dime, but of course they also have calling and texting plans available for people that use the same site frequently. I can do the same things I used to do on my cell phone like last minute get together for pizza and gaming.

With people complaining about the costs of cellphone services, it makes you wonder why more people aren’t doing what I’m doing. The cellphone companies after all are getting rid of contracts and trying to cut monthly costs for consumers when it comes to their cellphone bills. They know that something has to give when it comes to people having to pay over 100 dollars a month to be able to have enough data to use for their mobile devices.

Data has everything to do with modern communication, and this trend is only going to keep pushing forward. What are cellphone companies going to do about it? What are communication devices going to look like in the future? It seems as though the touchscreen smartphones and tablets have been around for quite some time. Time is the keyword here, as it’s only a matter of time before a new invention or new technology surfaces and takes over.

And that is precisely what makes it very intriguing because it could be that communication takes a huge step forward once we finally see the replacement for modern day smartphones.

Evolution of the Telephone

1444884433rfeliIn the late 1800’s, there were two inventors who designed devices that could transmit speech electronically. The two inventors were Alexander Graham Bell and Elisha Gray. The device would later be known as the telephone. Although both men tried to have their designs patented, Bell were able to patent his design first. After a legal battle was won by Bell, the evolution of the telephone began.

Brief Biography

Bell was born March 3, 1847 in Scotland. Both his father and his grandfather worked with elocutions. He was educated and encouraged to pursue a career in the same field. His in depth knowledge led him to not only invent the telephone, but to also teach the deaf.

From Telegraph To Telephone

Both the telegraph and the telephone electrically wired based systems; the telephone was a result of Bell’s attempt to perfect the telegraph. When Bell began the process of experimenting with the telegraph, the device had already been a way to communicate for over 30 years.

Even though it was a successful communication device, the telegraph was limited because it could only receive and send one message (Morse code) at a time. Bell’s understanding of music helped him to think of the possibilities of connecting the wires so multiple messages could be sent at one time. The harmonic telegraph was designed so that several notes or sounds could be sent at the same time.


By late 1874, Bell’s research had furthered to the point where it could potentially compete with breaking the monopoly that Western Union Telegraph Company had over the current communication system.

Bell then combined with his research with Thomas Watson who was an electrician. The two then began the process of creating a device that could electronically transmit speech. In order for the device to be a success, it would need a transmitter that had the ability to encase a membrane that would be able to handle different electronic currents and one receiver that could reproduce these currents into frequencies that were audible.

The First Sounds

In 1875 while experimenting with the device, Bell discovered that he could hear sound come across the wire. The sound was similar to the spring in a clock.

1876 marked the death of the telegraph and the birth of the telephone. Speech communication had evolved from a dot dash system to the ability to talk with electricity.

His journal entry described his success with his experiment with his new invention, the telephone. He uttered these famous words to his assistant Watson, “Mr. Watson. Come here. I would like to see you.”

The Candlestick

From the early 1890s to the late 1930s, the candlestick was a telephone that was actually two separate pieces. The mouthpiece was called the candlestick, but this style of telephone became outdated once manufacturers began making the unit a single piece.

The Rotary,The Pushbutton,The Cellular

The rotary replaced the candlestick, but as pushbuttons became popular in the 1960s and 1970s, the rotary slowly phased out.

Cellular phones, and within the past decade, smartphones have changed the way that people communicate electronically. Features, apps and other technological advancements have dramatically changed the first telephone designed by Bell.

Analog vs. Digital

The Difference Between Analog And Digital – Signals And Circuits

file0001051613418The difference between analog and digital is a broad topic. Generally, this topic can be divided into several subtopics, which can be divided into:

•    Analog and Digital Circuits
•    Analog and Digital Signals
•    Analog and digital waves and others

NOTE: even if digital systems have taken over analog systems, they still play a very role in electronic circuits. Moreover, they are used in many gadgets today dues to their advantages and their unique systems.

The Difference Between Analog And Digital Circuits And Signals

Analog Circuits

file2401239909435These circuits operate on continuous-valued signals. In other words, analog circuits apply a series of different circuits of analog signals to perform a particular desired intention or task. It takes time and a lot of effort to design an analog circuit; since every component has to be set by hand – because when it comes to designing, automated techniques applied on these circuits fail to make them efficient.

Benefits Of Analog Circuits

•    It does not offer conversions at the inputs
•    It does not offer any information loss related to signal conversions

The Limitation Of Analog Signals

•    The manpower available to design analog circuits is very low
•    It takes long to market the finished products
•    These circuits are custom made making them expensive and lack flexibility

Digital Circuits

142283313761rzwThe best thing about these circuits is that they operate on only two levels that are 0’s and 1’s: otherwise known as the binary number system. The good thing about digital signals is that they are very easy to design since automation production can be applied on them at various circuit levels.

Benefits Of Digital Circuits

•    They offer high degree of flexibility
•    The availability of manpower in designing

Limitation Of Digital Circuits

•    Some amount of information is lost during to conversion processes

Digital And Analog Comparison

To get an overall idea on the difference between digital and analog technology, it is important to compare the two in different fields of application.

•    WAVES: analog waves are denoted by sine waves; whereas digital waves are denoted by square waves.

•    REPRESENTATION: analog uses different continuous values to represent information; whereas digital uses discontinuous or discrete values to represent information

•    TECHNOLOGY: analog technology records waveforms the way they are; whereas digital technologies divide signals into a set of numbers and then record them

•    RESPONSE TO NOISE: analog systems are more likely to be affected by noise and surrounding factors influencing accuracy; whereas digital systems do not get affected by noise


file0001266688173With my blog, we will primarily be focusing on communication. There is so much that goes into communication and devices used for it.

Devices have evolved over the years, as excepted. We have gone from letter writing to radio to telephone and beyond in just a hundred years. Technology has been a sounding board for the growth in communication. We have taken great strides to give the people the best they deserve in communication.

We continue to give everything we have into creating a better world where we can understand each other more.

Join me as I travel through the aspects of communication and all it entails.
