| Abstract: | In order to make several communicators work normally within a short distance with similar frequencies,The effective method is applied high Q-value band-pass filters in both input-terminal and output-terminal of the receiver. In this article the design of a real-time tuning UHF electrically tunable filter based on single chip computer is given.And the hardware structure diagram and drivers, detection unit circuit design and flow diagram are also shown. |
