Radio noise - denpazatson (English spelling)
In wireless communications, this refers to irregular and generally unpredictable radio waves that mix with desired radio waves and disrupt reception. Radio noise is classified into continuous noise and impulse noise, focusing on its waveform. Noise that lasts for a long time and changes slowly over time is called continuous noise, while impulse noise that lasts for a short time is called impulse noise. Radio noise can also be classified according to the cause of its generation. When the source exists in nature, it is called natural noise, and when it comes from man-made objects, it is called artificial noise.
