Signal distortion refers to the alteration of a signal's original shape or characteristics during transmission. This can occur due to various factors such as interference, noise, or limitations in the transmission medium. When signals are distorted, the information they carry may become corrupted, leading to errors in communication. In digital communications, signal distortion can significantly impact the quality and reliability of data transmission. Techniques like equalization and error correction are often employed to mitigate the effects of distortion, ensuring that the received signal closely resembles the original. Understanding and managing signal distortion is crucial for effective communication.
