PURPOSE:To obtain a signal processor capable of generating a signal in which noise is securely removed. CONSTITUTION:A frequency analyzing means 3 inputs a signal mixed with noise and analyzes frequency, a signal detecting means 20 detects a signal part from the signal mixed with noise for which the frequency is analyzed, a noise prediction means 6 inputs the signal mixed with noise for which the frequency analyzed and predicts the noise of the signal part based on noise information in the past, a cancellating means 7 deducts the predicted noise from the signal mixed with noise for which the frequency is analyzed and a band synthesizing means 8 synthesizes the band of a cancelled signal. |
