Abstract
A signal transmission circuit of an electronic device is provided. The electronic device is coupled to a signal reception circuit of a host via the signal transmission circuit. The signal transmission circuit includes a driving circuit module and a signal detection module. The driving circuit module provides at least one initialized signal and a detection signal. The initialized signal is output prior to the detection signal. The signal detection module is coupled to the signal reception circuit via a signal detection terminal. The initialized signal reduces a signal reference level of a reception terminal of the signal reception circuit. The signal detection module determines the type of the transmission interface of the signal reception circuit according to whether the detection signal of the signal detection terminal satisfies a predetermined threshold value. Furthermore, a method for detecting the signal transmission interface is provided.
