In order to compensate the measurement error of measuring result caused by limited band of a vibration pick-up and its measurement system, a method for recovering the original input signal of the vibration pick-up using FIR transversal filter is presented. The coefficients of the FIR transversal filter was identified by using adaptive RLS algorithm while the output signal of the vibration pick-up was input into the FIR transversal filter. An inverse-convolution filter was acquired to recover the original input signal of vibration pick-up. The final results examined by serial different characteristic signals indicate that the method presented is effective and appears to have fine generalization ability.
