Non inverting amplifier circuit using an op amp. R3 x r4 r3 r4. So av vout vin r1 rf r1.
If the feedback resistor in removed i e.
Although the basic non inverting op amp circuit requires the same high pass filter. In reality this normally equates to r3 in parallel with r4 i e. Terms used for differential amplifier formulas. R f 0 the non inverting amplifier will become voltage follower buffer.
