Abstract

The present invention generally relates to disclose a waveform learning apparatus of remote controller. The waveform learning apparatus of remote controller includes a signal-receiving interface for receiving the household appliance remote controller signal. The signal-receiving interface connects to a microprocessor. The present invention utilizes the high operation ability of the microprocessor to perform the process of waveform digitizing on the received signal and then to store the waveform digitized data in a memory unit. Following, the present invention utilizes the signal-transmitting interface to transfer the remote signal to achieve the purpose of controlling the household appliance. The present invention can completely copy the signal of multiple remote controllers to replace the original remote controller, so the present invention provides with the advantages of easily learning, quick and precise.
