Signal loss refers to the reduction in strength of a transmitted signal as it travels through a medium, such as air or cables. This can occur in various forms of communication, including telecommunications, radio, and television. Factors contributing to signal loss include distance, interference from other signals, and physical obstacles like buildings or trees. In digital communications, signal loss can lead to degraded performance, resulting in slower data rates or dropped connections. To mitigate signal loss, techniques such as amplification, error correction, and using higher-quality cables or antennas can be employed, ensuring clearer and more reliable communication.
