At high inputimpedances, in practice both efficiency and bandwidth of a transformer will reduce.
实际上高输入阻抗的变压器,它们的效率和频带宽度都会下降。
2
Then the impacts of metal case size on the inputimpedances and patterns of antennas are discussed with the moment method.
进而结合实际的天线结构,运用矩量法计算了金属盒大小对天线阻抗和方向图的影响。
3
The element values of filters can be calculated by permutation method instead of the usual synthesis, i. e. successive complete and partial pole removals from the inputimpedances.
