Noise analysis is a research area that focuses on studying and quantifying noise in various systems or processes. This includes analyzing the sources of noise, its characteristics, and its impact on the overall performance of the system. Noise analysis is commonly used in fields such as signal processing, communications, electronics, and acoustic engineering. Researchers in this area use various techniques and tools to measure and analyze noise levels, identify sources of noise, and develop strategies to mitigate its effects. The ultimate goal of noise analysis is to improve the quality and efficiency of systems by reducing or eliminating unwanted noise.
