1. A method of encoding a high frequency signal, the method comprising:

  • extracting a coefficient by linear predicting a high frequency signal, and encoding the coefficient;

    generating a signal by using the extracted coefficient and a low frequency signal; and

    encoding the high frequency signal by calculating a ratio between an energy value of the high frequency signal and an energy value of the generated signal.
