Abstract

A signal auto-detection module and a method are described. The signal auto-detection module includes a first analog-to-digital converter, a second analog-to-digital converter, and a processor. When waked by a wake-up signal, the first analog-to-digital converter receives a first analog signal. When waked by the wake-up signal, the second analog-to-digital converter receives a second analog signal. The processor generates the wake-up signal. The processor selects a signal from the first analog signal and the second analog signal as a display signal. The processor examines the display signal to determine whether it is a proper signal before it is displayed.
