Abstract
The problem of the intrinsic origin of 1/f noise is considered. Currents an d signals consisting of a sequence of pulses are analyzed. It is shown that the intrinsic origin of 1/f noise is a random walk of the average time bet ween subsequent pulses of the pulse sequence, or the interevent time. This results in the long-memory process for the pulse occurrence time and in 1/f type power spectrum of the signal. (C) 2000 Elsevier Science Ltd. All righ ts reserved.
