Power spectra of the fluctuations decay with two distinct exponents (1/v_l and 1/v_h). For conductivity $\\sigma\\sim 0.1 e^{2}/h$, we find a third exponent (1/v_i) in the shortest samples, and non-monotonic dependence of v_i and v_l on \\sigma. We study the dependence of v_i, v_l, v_h, and the variances of corresponding fluctuations on \\sigma, sample size, and temperature.
