Signaalinhäiriö

Signaalinhäiriö, often translated as signal interference or noise, refers to any unwanted disturbance that affects the quality or integrity of a signal. This can occur in various forms of communication and data transmission, including radio waves, electrical signals, and even biological systems. The presence of signaalinhäiriö can lead to degradation of the received information, making it difficult or impossible to decode accurately.

Common sources of signaalinhäiriö include electromagnetic interference from other electronic devices, atmospheric conditions affecting radio transmissions, or physical imperfections in transmission media like cables. In digital systems, interference can manifest as bit errors, where a transmitted bit is incorrectly received. Analog signals might experience distortion or a reduction in their signal-to-noise ratio, making them harder to interpret.

Mitigating signaalinhäiriö is a critical aspect of many technological fields. Techniques like shielding, filtering, error detection and correction codes, and careful signal processing are employed to minimize its impact. The specific methods used depend heavily on the type of signal and the nature of the interference. Understanding and managing signaalinhäiriö is essential for reliable communication and accurate data acquisition.
