Unknown to many, digital signal processing has a wider impact in economic, social and global categories. From an economic perspective, digital signal processing generates revenue and has proven to be a source of much business for the future; this is where the future is heading. In the social context, digital signal processing has allowed us to evolve (and continue to evolve) with communications with virtually anyone 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 daily life.KeywordsDigital signal processing, social, economic, global, signalI. IntroductionWhen you think of digital signal processing, what comes to mind? Well, you might be thinking of digital signals, so cell phones? What about radio or even satellite television? The answer is yes, all of this is correct, but digital signal processing has a broader impact that goes beyond these everyday elements. Digital signal has been around for about 5 decades, since the early 1970s [4]. Analog has existed since the 1950s and takes the role of big brother of digital signals [5]. Digital was closely related to analog, but later diversified because it was more useful. Digital signal processing, defined by Wikipedia, is the mathematical manipulation of an information signal to modify or improve it in some way. In my opinion, the goal of digital signal processing is to convert signals, such as analog to digital and/or digital to analog. This conversion allows signals to be processed into numbers, which can be used for various...... middle of paper ......ion, whether audio, video or speech. It allows everyone to be connected to each other, an ever-evolving ease of communication. This is a global shift that is one of the fastest growing industries. Globally, digital signal processing is a science in constant use. It is used to communicate with world leaders and connect countries in times of war, disaster relief, as well as to achieve common goals between nations. Another use is for communicating with ships that sail the seas, and without this I believe many would be in grave danger. I view digital signal processing as a life-changing tool. We can do many great things with it, for example in communication and networking, and it can also be an extremely harmful tool. It depends on how it is used, but one thing is certain: digital signal processing is a rapidly growing technology with a vast future ahead of it...
