Description

ки  в куб 6 блока умножени  8, в результате чего формируетс  процесс xC-k), который гаэсле двухкратного интегрировани  на интеграторах 3 и 4 представл ют собой процесс, опнсьшаемын приведенным уравнением, причем входы блока умножеш;  8 соединены с выходами шггегратора 3 и квадратора 7, вход которого соедини с выходом интегратора 4, т,е. с выходом всего устройства.ki in cube 6 of multiplication unit 8, as a result of which the process xC-k is formed), which, after double integration on integrators 3 and 4, is a process determined by the above equation, and the inputs of the unit are multiplied; 8 are connected to the outputs of the schedger 3 and quadr 7, whose input is connected to the output of the integrator 4, t, e. with the release of the entire device.

Это дает возможность реализовать стайшьный и ишрокодиапазонный стохастический блок,  вл юишйс  основным узлом любого имитатора канала, что позвол ет с)ацестеенир повысить качество рабочих характеристик устройства.This makes it possible to implement a stationary and isofracted stochastic block, which is the main node of any channel simulator, which allows the c-tester to improve the quality of the device's performance.
