Webrier life time, the resultant noise spectrum will be a superposition of several distributions described by (11.6). Therefore, the spectral distribution of noise can be used to investigate various generation- ... The 1/f noise (flicker noise) sometimes is considered to be responsible for the long-term device parameter fluctuation. 11.2.5oise 1/ 2N f WebConventional spectrum analyzers that sweep a narrow filtered band over the signal have good signal-to-noise (SNR) since they are narrow band instruments. Unfortunately, …
