Attenuation refers to the gradual loss of intensity or strength of a signal as it travels through a medium, such as air, water, or a material. This phenomenon is typically observed in communication systems, where signals can become weaker due to factors such as distance, obstacles, or interference. Attenuation can impact the quality and reliability of communication transmissions and is a key consideration in designing and optimizing communication networks. Researchers in the field of attenuation study various techniques and methods to minimize signal loss and improve the performance of communication systems.
