Web根据巴塞伐尔定理，我们可以定义功率谱密度(PSD，power spectrum density) 图10 功率信号得到功率谱密度 图10中P(f)就是定义的功率谱密度。 WebJun 2, 2024 · In the case of white noise, the PSD equals 1 for all frequencies. White noise in signal analysis, which has equal power density at each frequency, corresponds to white light in physics, which has equal power density at each frequency. A PSD with a single spike at 0Hz is likely caused by the presence of a large DC offset in the signal.
