Web25 jul. 2024 · As the gain is dependent on the resistors and the formula is Av = 1 + (Rf / R1) In our case, the gain is 3 and the value of R1 is 1. 2k. So, the value of Rf is, 3 = 1 + (Rf / 1.2k) 3 = 1 + (1.2k + Rf / 1.2k) 3.6k = 1.2k + Rf 3.6k - 1.2k = Rf Rf = 2.4k After amplification, the output voltage will be Av = Vout / Vin 3 = Vout / 2V Vout = 6V WebThe bridge may be classified as balanced when the voltage between R1 and R2 equals the voltage between R3 and R4. The bridge voltage will equate to 0 at this point, with R1/R2 = R3/R4. If the bridge is balanced, the current will be zero as well. If we know the bridge is balanced, we can discover the value of R4 with the formula: R4 = R3 * R2 / R1 WebHomework #6 Solution Fall 2010 4 6. Consider an amplifier having a midband gain AM and a low-frequency response characterized by a pole at s=-ωL and a zero at s=0.
