Nowadays, the world is full of signals that consist of natural and manmade. Electrical signals are everywhere since they utilize in communications, entertainment devices, imaging devices, and computers. Digital Signal Processing Techniques is used in everywhere in the areas of the audio signal, speech processing, SONAR, voice recognition and financial signals.
The process of analyzing and modifying a signal to optimize and improve its efficiency is known as Digital Signal Processing. It involves applying several mathematical and computational algorithms to analog and digital signals to produce a signal that is higher quality than the original signal. As well as, it refers to various techniques for improving the accuracy and reliability of digital communication.
Applications of Digital Signal Processing such as audio compression, audio Signal Processing, speech processing, and biomedicine so on.
Audio Signal Processing: It is a subfield of Signal Processing which is a concern with electronic manipulation of audio signals. As audio signal may represent in either analog or digital format, processing may occur.
Speech Processing: It is the applications of digital signal processing for the processing and analysis of the signal. Some applications of signal processing include speech coding, recognition, verification, and enhancement.
Audio Compression: This type of compression that reduces the level of the audio signal if it is amplitude exceeds a certain threshold.
Video Compression: It is performed via a video codec which works on one or more compression algorithms. Video Compression is done by removing repetitive images, sounds from the video. Similarly, it will remove all data to reduce the size of the video file.
Biomedicine: It aims at extracting significant information from biomedical signals. Usually, they are detected through electrodes or transducers.
Here some major Challenges of Digital Signal Processing Techniques such as,
Machine Learning: Signal Processing is a domain where we apply different techniques to filter classifying on a process signal. While learning is a technique to make computer/system learn on different patterns or classes by which it can organize the inputs with Internet of Things.
Medical Imaging: Medical Imaging is the technique and process of creating the visual representation of the interior of a body for clinical analysis and medical interventions as well as visual representation of the functions of some organs or issues.
Graph Signal Processing: Graph Signal Processing has the aims to develop tools for processing data defined on variable graph domains. The complexity of such network and interactions means that the data now resides on irregular and complex structure that do not lend themselves to standard tools.
A final year project in Digital Signal Processing Techniques that will help you in plenty of ways such as, getting to know everything about it, and compliments your theoretical also practical knowledge of the subject. One of the great benefits of doing a digital signal processing project is that it will expose you to a broader range of this industry.
