Lecture
This lecture covers the basics of noise in electronics, including average power, rms value, deterministic and random signals, noise amplification, and filtering. It explains the impact of noise on electrical systems, the concept of signal-to-noise ratio, and the origins of noise in electronic components. The lecture also delves into amplitude distribution law, noise power spectral density, and the characteristics of deterministic and random signals. Additionally, it discusses the average power and rms value of both deterministic and random signals, as well as the concept of power spectral density. The instructor illustrates these concepts with examples and explores the correlation between noise sources, emphasizing the importance of understanding noise in electronic systems.
