Wireless domestic network self adaptive pass band filter having parallel mounted different frequency filters prior amplifier and frequency selector detecting/selecting frequency.

摘要

The self adaptive pass band filter has a receive antenna (1) connected to an amplifier (2) and mixer (4) and frequency synthesiser (5). The auto adaptive mechanism (3) has filtering (31,32) at two different frequency bands and a frequency selector (33,34) selecting the frequency band as a function of the frequency signal received.
