Crosstalk refers to the unwanted transfer of signals between communication channels, which can lead to interference and distortion. This phenomenon is commonly observed in electronic devices, such as telephones and audio equipment, where sounds from one channel can unintentionally mix with another. Crosstalk can degrade the quality of conversations or audio playback, making it difficult to understand the intended message. In telecommunications, crosstalk can occur in wired systems, like copper cables, or wireless systems, such as cellular networks. Engineers work to minimize crosstalk through various techniques, including shielding and signal processing, to ensure clearer communication and better performance in devices.
