摘要 |
<p>The transmission system allows signals to be transmitted between two identical devices in both directions simultaneously. The propagationn of the IR light between the 2 devices is effected directly or using relfection, refraction or diffraction. Each device has a single stabilised frequency oscillator (4) for both the transmission and reception function, with a low-pass filter (10) determining the frequency spectrum and a bandpass filter defining the reception spectrum. -</p> |
