Unknown to many, digital signal processing has a broader impact in economic, social and global categories. From an economic perspective, digital signal processing generates income and has proven to successfully bring many businesses into the future; it's where the future is going. In the social context, digital signal processing has allowed us to evolve (and continue to evolve) with communications to virtually everyone in the world. It connects millions of people around the world, which brings us to the global aspect. Digital signal processing is relevant because it has become a necessity. Many people only think about cell phones; they don't know that digital signal processing is used in everyday life.KeywordsDigital signal processing, social, economic, global, signalI. IntroductionWhen you think of digital signal processing, what comes to mind? Well, you might be thinking about digital signals, so cell phones? What about radio or even satellite television? The answer is yes, all of this is correct, but there is a broader impact of digital signal processing that goes beyond these everyday items. The digital signal has existed for about 5 decades, starting in the early 1970s [4]. Analog has existed since the 1950s and takes on the role of the big brother of digital signals [5]. Digital became intertwined with analog, but then branched out because it was more useful. Digital signal processing, defined by Wikipedia, is the mathematical manipulation of an information signal to modify or enhance it in some way. As I see it the goal of digital signal processing is to convert signals, for example from analog to digital and/or digital to analog. This conversion allows signals to be processed into numbers, which can be used for a wide range of documents, be it audio, video or speech. It allows everyone to be connected to each other, an ever-evolving ease of communication. It is a global change that is one of the fastest growing sectors. Globally, digital signal processing is constantly used in science. It is used to communicate between world leaders and connect countries for war, disaster relief, and common goals between nations. Another use is for communication with ships that sail the seas and, without it, I believe many would be in grave danger. I consider digital signal processing to be a life-changing tool. We can do a lot of great things with it, such as communications and networking, and it can also be an extremely malicious tool. It depends on how it is used, but one thing is for sure: digital signal processing is a rapidly growing technology with a vast future ahead of it..
