We have observed in experiments with a driven nonlinear electrical resonator that the fluctuations in the "noisy precursor" to a period-doubling bifurcation are phase dependent and that the noise is deamplified in one of the phases. This is a classical effect analogous to "squeezing" which normally refers to deamplification of quantum noise. Preceding the period-doubling bifurcation a "noise rise" similar to that observed in Josephson-junction parametric amplifiers evolves and the noise deamplification ceases. This phenomenon and the "noise rise" appear to be related as successive stages in the development of a bifurcation in a nonlinear system in the presence of noise.
