The method of calculation of the correcting chain did not change, conditions – former since the type of the transistor did not change. The transistor of the entrance cascade is similar to the transistor of the preterminal cascade therefore parameters of a normalization did not change. Tabular values former:
The device considered in this work can be put widely into practice. The television receiver, system of indication of radar station and other devices of indication can be examples.
The method of calculation of the correcting chain did not change, conditions – former since the type of the transistor did not change. The normalization of elements of a chain is carried out for the weekend the capacity and resistance of the generator. Tabular values of rated elements the former:
Proceeding from the specification, the device has to provide distortions no more 3db. As three cascades are used, everyone can bring no more 1db distortions in the general AChH. These requirements impose restrictions on face values of the elements bringing distortions.
As the operated active resistance the KT 316A low-power transistor with average coefficient of transfer of current of the Tension base 5 on collector chain resistance on a direct current is chosen there has to be more than 1 V, in this scheme it is accepted for 24 Century.
Let's consider two schemes of realization of the output cascade: resistive and throttle. The choice of this or that scheme is feasible on the basis of the obtained data of calculation. Criterion of a choice – optimum power characteristics of the scheme. Also we will choose the transistor meeting requirements of a task.
