Реферат: The active low pass filter has an active bandstop filter with an amplifier (17) and a passive frequency-dependent network (10) earthed via a capacitor (29). A passive RC low pass filter (22, 23) is connected to the input side of the passive frequency-dependent network. The active bandstop filter contains three series capacitors (11-13) shunted by a resistor (14). A resistive voltage divider (15, 16) shunts the middle capacitor (12) and its tapping is connected to the tapping of a secoind voltage divider (19, 20) in series with the amplifier's emitter.
