Abstract
The present invention provides a micro-controller, a processing method and device for power line carrier signal reception, where the method includes: an analog mixer mixes received power line carrier signals, an analog filter filters the mixed power line carrier signals, an analog-to-digital converter converts the filtered signals, a digital mixer mixes converted signals, a digital filter filters the mixed signals and a digital demodulator demodulates the filtered signals to obtain base band data. The present invention also provides a corresponding device and a micro-controller including the device. The technical solution of the present invention can modulate the carrier signals of any frequency to a fixed frequency through two-stage frequency mixing, so that demodulation of power line carrier signals with any frequency is possible.
