Вариант №4.

fc = 4 кГц

f0  = 22 кГц

Выберем величину емкости, равную C = 1мкФ

Из формул fc = 1/ 2πRC, f0 = 1/ 2πRC получим R:

Rc = 1/ 2πCfc = 1/(2*3.14*1*10-6*4*103) = 40 Ом;

R0 = 1/ 2πCf0 = 1/(2*3.14*1*10-6*22*103) = 7,2 Ом;

Промоделируем в MicroCAP фильтр нижних частот:

Схема фильтра нижних частот

Частота среза fc = 3,978 кГц

Промоделируем фильтр верхних частот:

Схема фильтра верхних частот

Частота среза fc = 4,015 кГц

Промоделируем полосовой фильтр:

Схема полосового фильтра

Резонансная частота = 24,57 кГц

Для определения левой и правой резонансной частоты возьмем максимальную точку на графике и разделим ее значение на .

332.484/1.414 = 235.134

Левая частота среза = 6,68 кГц

Правая частота среза = 73,26 кГц
