Kõrgsagedusmüra

Kõrgsagedusmüra, also known as high-frequency noise or RF noise, refers to electromagnetic interference occurring at frequencies above the audible range. This type of noise is typically generated by electronic devices and systems operating at radio frequencies, such as radio transmitters, mobile phones, Wi-Fi routers, and certain industrial equipment. Unlike audible noise, which is perceived by the human ear, high-frequency noise is electromagnetic radiation.

The presence of high-frequency noise can affect the performance and reliability of electronic circuits and systems. It can lead to signal degradation, data corruption, and malfunctions in sensitive equipment. Common sources include switching power supplies, digital circuits, and motors. Shielding and filtering techniques are often employed to mitigate the effects of high-frequency noise. Proper grounding and layout of electronic components are also crucial in minimizing its generation and propagation.

In some contexts, "kõrgsagedusmüra" might also refer to unwanted high-frequency components within an audio signal that are beyond the typical human hearing range. While inaudible, these components can sometimes be processed by audio equipment and potentially affect the overall sound quality or introduce artifacts in digital audio processing. Managing these high-frequency elements often involves employing filters to remove or attenuate them.
