Description

ции порогового элемента 8. Выбросы напр жени  с выхода порогового элемента нормализуютс  по амплитуде и длительности формирователем 9 и регистрируютс , частотомером 10.threshold element 8. The voltage spikes from the output of the threshold element are normalized in amplitude and duration by the driver 9 and recorded with a frequency meter 10.

На фиг. 2 иллюстрируетс  принцип регулировани  частоты выбросов сигнала Е ( путем изменени  уровн  селекции Un- Очевидно , что при изменении уровн  селекции Un (фиг. 2,а) средн   частота сигнала с выхода формировател  F(Un,u) также измен етс .FIG. Figure 2 illustrates the principle of controlling the frequency of the E signal emission (by changing the Un-selection level. Obviously, when the Un selection level changes (Fig. 2, a), the average frequency of the signal from the output of the former F (Un, u) also changes.
