pinapahnap po kasi ung i using nodal analysis...asko ko lang po wat po gagamitin ko na voltage?ung 4 na peak or ung 2sqrt(2) na rms?
la na po ba pakialam ung cos sa mathematical like finding the vout ng opamp??

yung Vout ng opamp mo related pa rin diyan sa input voltage mo, as well as yung output current.

yong Vin mo yon din ang Vout mo multiply mo lang yong gain ng op-amp, X3 ata ang amplification factor ng diagram mo medyo malabo na ang formula ng gain ko...non-inverting po yang op-amps sa ckt....

pure resistor yong tatlong nasa dulo kaya wala kang problema sa voltage at current shift....

tama si sshrekk, ang kailangan mo lang malaman yung equation ng gain, tapos sa resistor. tapos substitute mo na yung actual voltage na 4 cos(2t).

hindi mo kailangang gumamit ng RMS or Peak.

Non-inverting amplifier, hanapin mo lang gain, wala naman phase shift yan so yung dc component lang ang magbabago.
