Abstract

PURPOSE:To make the characteristics of 1/f noise for the variance in the amplitude, by applying noise voltage to a gain control circuit so that the gain is controlled according to the change in the amplitude of the components in a prescribed frequency range. CONSTITUTION:The noise voltage No(t) obtained from a noise generator 1 is branched at a branching point 2 into two; one is taken as the input signal of a gain control circuit 3, and another is fed to a band-pass filter 4 to take up a prescribed frequency band component V(t), from which a voltage waveform A(t) according to the amplitude of V(t) is obtained by a rectifying circuit 5 and a low-pass filter 6, and this is taken as the control signal of the gain control circuit 3. Thus, fluctuation noise expressed as A(t)No(t) is obtained as the output signal of the gain control circuit 3.
