try looking for Multiple Feedback Topology. yan ang topology niyan.

http://www.ecircuitcenter.com/Circuits/MFB_bandpass/MFB_bandpass.htm

eto isa. for more in-depth discussions try reading "Opamps for Everyone" a TI Application Note about Opamps. nasa latter chapters yung filters. IIRC, Sallen Key and Multiple Feedback Topology ang na-discuss dun.

active filter b yan

mukang nakakaloko ah

may binigay kasi sakin n ckt

part lng yan nung buong ckt. e, ganun dn ung iba... sa paint q nga lng nalagay.. para madali.

try mo muna sa multisim ..... tignan mo yung output niya kung ano yung waveform

here's the Multiple Feedback Topology Bandpass filter. as to kung ano ang reason bakit linipat yung R1B sa Vout, sa computation na lang makikita.

try nodal analysis para maderive formula ng output/input transfer function.

inverting OP-AMP po yan yan din yung design sa amplifier at puwede rin frequency bypass filter depends nalang dun sa feedback resistor mo pag resistor lng yung nasa feedback ito ay amplifier lng pero pag with capacitor bypass filter na ang lalabasan depende sa capacitance na lalagay mo para sa frequency
