1. A signal re-driving device, comprising:
a receiving circuit;
a modulation circuit, coupled to the receiving circuit;
a sending circuit, coupled to the modulation circuit; and
a mode control circuit, coupled to the receiving circuit and the modulation circuit,
wherein the receiving circuit is configure to receive a first signal,
the mode control circuit is configured to detect an analog signal feature via the receiving circuit and control the modulation circuit to enter a first mode according to the analog signal feature,
the modulation circuit is configured to modulate the first signal and output a second signal in the first mode,
the sending circuit is configured to send the second signal, and
the mode control circuit is further configured to detect a digital signal feature via the receiving circuit and control the modulation circuit to switch from the first mode to a second mode according to the digital signal feature,
wherein the first mode is a normal operating mode and the second mode is an energy-saving mode or a standby mode.
