Patent ID: 7986797

Claim:
A signal processing system comprising a first signal processing apparatus in which an input signal is processed and stored and a second signal processing apparatus in which an input signal is processed and output, wherein: said first signal processing apparatus comprises: first-signal input means for inputting a first signal having a broad range of frequency components; second-signal input means for inputting a second signal in the first signal, the second signal having a narrow range having suppressed high frequency components; extracting means for extracting high frequency components from the first signal input by said first-signal input means; first determining means for determining each first class code based on the second signal input by said second signal input means; and storage means for storing, for the first class code determined by said first determining means, the high frequency components extracted by said extracting means; and said second signal processing apparatus comprises: third-signal input means for inputting a third signal having a narrow range having suppressed high frequency components; second determining means for determining a second class code based on the third signal input by said third signal input means; combining means for combining the high frequency components stored in said storage means, which correspond to the second class code determined by said second determining means, and the third signal input by said third-signal input means; and output means for outputting the combined signal generated by said combining means.
