OPTICAL WAVELENGTH DEMULTIPLEXER FOR A VIDEO PASSIVE OPTICAL NETWORK |
摘要 |
In a system where a second signal interferes with the detection of a first signal at an input, in which the second signal is composed of a low frequency component and a portion of the frequency spectrum that is higher than that of the first signal, then both signals are processed to eliminate such interferenceby filtering the second signal to eliminate the portion of the frequency spectrum that is higher than that of the first signal and eliminate the low frequency component of the second signal. Advantageously, such processing is done without affecting any low frequency component of the first signal.
