radio frequency current 中文意思是什麼
radio frequency current
解釋
射頻電流-
This high frequency alternating current produces the high frequency radio waves mentioned in the previous chapter.
這種高頻交流電流產生前一章提到過的高頻無線電波。 -
Passive tags do n ' t haven a power supply but a minute electrical current by an incoming radio frequency provides enough power for the tag to send a response
無源標簽並無電源,由外來的無線電頻提供微電流,為標簽提供足夠電力以作回應。 -
The lower resistance should select properly, too big to make radio frequency signal drive collector current too little, too small to make amplifier instable easily
下偏電阻要選取適中,過大會使射頻信號推動集電極電流的能力過小,過小容易使放大器不穩定。
