What is Types of Noise in Communication Systems about?

Noise is always present in electrical communication systems and can obscure signals. There are two main types of noise: man-made noise from sources like motors and natural noise from thermal and atmospheric sources. Thermal noise, also called Johnson or white noise, is caused by random electron motion and has a constant power spectral density across all frequencies, making it difficult to eliminate. Noise figures and temperatures are used to characterize the noise performance of components and systems.
