PURPOSE:To provide a signal supppressing device which can perform high-speed signal processing without using a high-speed DSP as to a signal suppressing device which suppresses signal components other a target component. CONSTITUTION:The signal suppressing device which has a 1st filter which electrically simulates a transmission system A for physical phenomena such as a sound, vibration, and electricity, inputs a signal correlative with a signal inputted to the transmission system A to the 1st filter, and approximates the signal passed through the transmission system A to a target value under the influence of the output of the 1st filter upon the signal passed through the transmission system A; and the 1st filter is divided into plural filters 11-13, which consist of individual DPSs (11)-(13). Then outputs are calculated individually by the divided filters 11 13 and individual calculation results are gathered to obtain the same value as a value calculated without dividing the 1st filter. |
