1. method of using the controlled gain amplification input signal may further comprise the steps:

  • Provide output signal, the input signal that its representative is amplified by initial gain;

    Judge the signal level of described input signal or described output signal;

    Described signal level and threshold level are compared;

    If described signal level is lower than described threshold level, then use the adaptive control characteristic to upgrade initial yield value;

    AndIf described signal level is higher than described threshold level,, use fixedly control characteristic or adaptive control characteristic renewal initial yield value respectively according to described signal level;

    Described adaptive control characteristic is relevant with described signal level, and described fixedly control characteristic and described signal level are irrelevant.
