REMOTE CONTROL SYSTEM, LIGHTING SYSTEM AND FILTER |
摘要 |
The remote controller incorporates a commercially available transmitter and receiver which reliably functions in the presence of infrared noise having frequencies at and about the carrier frequency of the transmitted signal. The remote controller receiver outputs a demodulated signal and a filter acts on the demodulated signal to remove noise present in the demodulated signal caused by e.g. an electric lamp by comparing measured time intervals between leading and trailing edges of the demodulated signal to predetermined values defining data elements.
