while there was no complete change in brain metabolism, they found a 7 percent increase in brain metabolism in the region closest to the cell phone antenna when the phone was on。相关知识点: 试题来源: 解析 is no try to need to have learned 56 57 58 59 60 61 62 63 64 65 66 67 68...
Higher antenna gain in dBi extends the communication range for a given transmit power level. Each 3 dBi increase approximately doubles the range under line of sight conditions. What cable type should be used for gateway antennas? Low-loss coax cable such as LMR-400 is recommended for gateway ...
make good 1. To carry out successfully: made good his escape. 2. To fulfill: made good her promise. 3. To make compensation for; make up for: made good the loss. 4. To succeed: made good as a writer. make hay To turn to one's advantage: The candidate's opponents made hay of ...
For use with RF antennas, baluns are needed where a balanced antenna such as a dipole is used. The most convenient form of feeder to use is coaxial cable as this can be routed far more conveniently along antenna towers, or poles, along the ground and through buildings, etc without the ...
An antenna tuning unit, ATU or antenna tuner is an item consisting of inductors and capacitors that is used to tune an antenna so that it matches the feeder and reduces the SWR.

If there is any problem in the middle between the transmitter / receiver and antennas - such as a fold or infiltration of water - half ends with the impedance mismatch. So, part of the signal which ideally should leave by the antenna, then returns reflected!
For the antenna, it is important to understand how efficient the antenna is at transitioning the signal to and from the air. As we’ll explain later, this is determined by using a VNA to measure the return loss or VSWR of the antenna. Looking at the right side of Figure 4, the up-...
This gives you good results in quiet scenes where not much is moving, because there is nothing blurred then. You could call it: Motion Blur This seems to me a much better idea than Blending, but unfortunately I don't know any filter or program that can do it. The idea is: Blur the...
