Measurement of low-frequency noise spectrum and computation of its parameters
Luo Tao, Yong Xu, Dai Yisong, Shi Yaowu · 2002
In this paper, a low-frequency noise spectrum testing system is presented, its measuring range is 0.25 Hz approximately 100 kHz, and accuracy is higher than 4%. Moreover, the white noise level and corner frequency are computed by applying the weighed least square method.>
