Description
поступает iia сумматор 7, На другой вход которого это же напр жение поступает через фильтр 8, усилитель 9 и инвертор 10, которые вместе с сумматором 7 образуют фильтр. Этот фильтр позвол ет получить нулевой коэффициент передачи на необходимой частоте, котора определ етс параметрами фильтра 8 и коэффициентом усилени усилител 9. Устройство устойчиво при выполнении услови iia adder 7 enters, at the other input of which the same voltage enters through filter 8, amplifier 9 and inverter 10, which together with adder 7 form a filter. This filter allows to obtain a zero transmission coefficient at the required frequency, which is determined by the parameters of the filter 8 and the gain factor of the amplifier 9. The device is stable when the condition
l-Q/F(cp«)(/Co-I)0.l-Q / F (cp «) (/ Co-I) 0.
где T RC--посто нна фильтра 8,where T RC is a constant of filter 8,
Ко - коэффициент усилени усилител 9, сро - разность фаз генераторов 1 и 4.Co is the gain of amplifier 9, the phase difference between the generators 1 and 4.
Увеличить запас устойчивости можно, примен в качестве фильтра низкой частоты пропорционально-интегрирующий фильтр.Increase the stability margin can be applied as a low-frequency filter proportional-integrating filter.
