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

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

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
