  • Publication number: 20080063220
    Abstract: An audio control method and audio processing system utilize an ADC to sample an analog audio input signal and convert it to a digital audio signal. A control module determines input signal level from the digital audio signal. Based on different input signal levels, output gain range of the amplifier can be set. In this way, the present invention can prevent speakers being burned out or volume being too low.

  • Publication number: 20080037296
    Abstract: A green-mode flyback pulse width modulation apparatus adopting a bipolar transistor structure IC process is used in a power supply. An oscillator circuit outputs a periodic clock signal to a control terminal of a power switch through an amplifier circuit for periodically turning on the power switch. A latch circuit is connected to the oscillator circuit, the amplifier circuit, the power switch and a feedback terminal of the power supply for periodically pulling down the potential at a control terminal of the power switch in response to a feedback signal generated by the feedback terminal to turn off the power switch and continue suspending the operation of the oscillator circuit when the power supply is at a light load, and will resume the output of the oscillator circuit till the potential of the feedback signal potential drops, so as to achieve the green-mode function.
