minimum-signal level 中文意思是什麼
minimum-signal level
解釋
最低信號電平-
It works at high frequency with a selectable pin outside ; the working frequency is fixed at 640k / 1. 2mhz. so far as the output signal of the single - chip ic is concerned, the maximum time proportion of its high level is 88 percent, but the minimum one is 10 percent
該控制器為pwm脈沖寬度調制方式;電路正常工作溫度范圍為- 20oc 85oc ;工作開關頻率根據外圍電路輸出電壓需要為640k / 1 . 2mhz可選;輸出信號的最大占空比為90 % ，最小占空比為10 % ，晶元主要應用於lcd電壓電源管理設備。 -
For the receiver which uses the intermediate frequency real signal output manner, a good frequency plan should guarantee the transition band of the “ spectrum blocks ” which produced by the sampling as wide as possible, so as to ease the burden of the base - band signal processing to the minimum level. it has not been particularly analyzed in the former references about receiver design, and the main
在以往有關接收機設計的文獻中很少對此進行過詳細的分析，其主要原因是大多數接收機系統的信號帶寬較窄（通常在2 、 3mhz以下） ， fif和fs受到的限制較少，可以很輕易的保證采樣之後各「譜塊」有足夠的過渡帶寬。 -
The minimum dose of lps inducing mbd3 expression was 1. 5 g / g, although the mbd3 mrna level tended to be dose - dependant, there were no distinct difference between the relative pixel values of the autoradiographical signal
本實驗的確定的lps最小誘導劑量為1 . 5 g g體重。 mbd3mrna水平隨劑量增加呈逐漸增加的趨勢，但凝膠成像系統分析放射自顯影帶的相對灰度值間無顯著差異。
