A suppression system of background noise of speech signals uses an adaptive filter of long-time and short-time statistical characteristics of the speech signals. Since the statistical characteristics of the speech signals vary with time, the associated coefficents of the filter also have to be adjusted according to the varitation of the speech signals to eliminate the unnecessary background noise. High frequency attenuation of the speech signals is compensated for by passing the signal through a high frequency booster to elevate the degree of brightness of the speech signals and to improve their quality.

A method for arc welding can control the increase slopes of the short-circuit current and the inflection point of the increase slopes in the welding start period to be smaller than in the steady-state welding period. Thus, the increase slopes of the short-circuit current and the inflection point are made different between the welding start period and the steady-state welding period, thereby reducing sputtering in the welding start period.

In servomechanisms, like for example used in disk drives, disturbances, for example, friction, shock and vibration, prevent the system positioning accuracy from further improvement. These disturbances occur in a relatively low-frequency range compared to the electrical dynamics. In the present invention, an acceleration feedback control loop using a frequency-separated acceleration soft sensor (350) replaces the conventionally used current control loop in the low frequency range, where the disturbances occur, so as to attenuate the influence of the disturbances enclosed in the loop. The current feedback continues to manage the electrical dynamics in the high-frequency range. Estimating the required acceleration signal by a soft sensor (350) eliminates the need for physical accelerometers, which reduce system reliability and increase system cost. The acceleration feedback control loop constructed with the obtained acceleration signal also makes the system more robust to the parameter inaccuracies and variations within the loop. This invention can be easily implemented with either software or hardware.
