What absolute voltage gain can be expected from the circuit in Figure E7-3 when R1 is 1,800 ohms and RF is 68 kilohms?

Schematic of a circuit with a triangular three-terminal component, resistor R1 at the input, and resistor RF connecting output to input.
  1. 1
  2. 0.03
  3. 38پاسخ درست
  4. 76

توضیح

Absolute gain of the inverting stage is RF / R1 = 68,000 Ω / 1,800 Ω = 37.8, which rounds to 38. A gain of 76 is twice that value and 0.03 is the reciprocal.
