✦ Synopsis

The approach for generating a broad-band colored noise is proposed, which allows the transition between ''red'' and ''green'' noise. The rectification of the noise with different colors characterized by the net current of a Brownian particle moving in a ratchet-like potential is studied by using the digital simulation. The present noise is also compared with the harmonic noise. The results show that the average current reverses sign when the external noise is filtered off in the region of low frequencies to a sufficient extent. Finally, a parameter plane of the noise with the numerically estimated line of the current reversal is plotted.
