Signal processing, encompassing both analog and digital realms, forms the backbone of various technological applications. The article begins by distinguishing analog and digital systems, highlighting their respective roles in manipulating and interpreting signals. A detailed examination of signal theory follows, elucidating key concepts such as signal representation, Fourier transform, and the Nyquist theorem. The discussion extends to data processing, unveiling techniques used in image processing and audio analysis. Special attention is given to speech processing, a specialized domain with applications ranging from speech recognition to synthetic speech generation. As we traverse the landscape of signal processing, the article underscores the pivotal role these systems play in modern technology, paving the way for future advancements in communication, data analysis, and human-machine interaction.}, pages = {1--6}, url = {http://thejournalshouse.com/index.php/SignalProcessing-Applications/article/view/983} }
