Signal processing is a branch of electrical engineering and applied mathematics that deals with the analysis, modification, and synthesis of signals. Signals are all around us—any physical quantity that changes in time, space, or any other independent variable. Examples of signals include sound waves, electromagnetic waves, and sensor data (Zhang in Modern signal processing. Walter de Gruyter GmbH & Co KG [1]). Real-time signal processing refers to the analysis of signals in real-time, which means that the processing must be performed in a timely manner so that the output data is available as soon as possible. Real-time signal processing is crucial in various applications, including audio and video processing, control systems, and signal analysis.
