An image-reject hairpin bandpass filter used in Ku-band low noise block (LNB) is designed, and optimized in the paper. The designed detail of the filter is explained and the image-reject is illustrated theoretically. According to the research, under the condition of reducing the size as small as possible, the hairpin filter used in Ku-band LNB we designed not only can satisfy the demands from bandwidth...
Energy efficiency is the most important issue in all facets of wireless sensor networks (WSNs) operations because of the limited and non-replenishable energy supply. And WSNs are deployed in environments where sensors can be exposed to conditions that might interfere with the sensor readings. Moreover, a variety of sensors may be attached to WSNs to monitor the environment. Data aggregation, eliminating...
Hydraulic system is the important component of missile armament system, and its performance has determined the viability and reliability of the armament system. So it is very significant to diagnose its faults during its working period. But it will cause the substantive training expense to carry out the study in the actual equipment, and it is disadvantageous to the study of fault diagnosis technique...
