Secondly , we make an in - depth study and analysis in allusion to the given oscillatory circuit - butler common base harmonic circuit . the detailed analysis of the dynatron which is the main noise source in the oscillatory circuit is also made , including how excitation affects the dynatron and crystal 然后針對特定的振蕩電路結構-串聯(lián)型巴特勒共基振蕩電路-進行深入的研究和分析,并對主振電路中主要的噪聲源-三極管進行的深入分析,包括激勵對三極管及晶體的影響。
In this paper , the oscillatory circuit and synthetic circuit are analyzed theoretically at first and the main parameters of sythetic circuit under the conditions of the different current grades are gotten , that is not only the parameters " basis of synthetic circuit test , but also the important references of studying computer - testing system for current measurement of current - source in synthetic circuit 本文首先對振蕩回路和合成回路進行了理論分析并確定了在不同電流等級條件下合成回路中的各主要參數(shù),這不僅為合成回路試驗提供了參數(shù)依據(jù),同時也為合成回路中電流源電流信號計算機測試系統(tǒng)的研制提供了重要參考。
First , the frequency - temperature ( f - t ) characteristic of quartz crystal resonator is analyzed . then , the frequency - temperature ( f - t ) characteristic curve of at - cut quartz crystal resonator ( at cut angle : 3 = 0 , 1 = 35 6 ) is obtained based on analyzing the christoffel equation describing flexibility sound wave in solids , which serves as the theory basis used for temperature compensated , from which the actual circuit of oscillatory circuit is designed 首先對石英晶體諧振器的頻溫特性進行分析,然后通過求解描述固體中彈性聲波的christoffel方程,得到其在切角3 = 0 , 1 = 356處也即at切石英晶體諧振器的頻率溫度特性曲線,這是本文進行溫度補償?shù)睦碚撘罁?jù)。
