A. 560hz
B. 390khz
C. 25.6khz
D. 1.5Mhz
Answer:A
Calculate the bandwidth for the given circuit.(Where the 741 op-amp has gain of 200000).
A. 560hz B. 390khz C. 25.6khz D. 1.5Mhz
Explanation: Gain of the amplifier AD = -{[1+(2*R4/R5)]*(RF/R1)} = -{[1+(2*5kΩ/2.5kΩ)]*(3.9kΩ/500Ω)} (since, RF = R3 and R2 = R1).
