An RC phase-shift oscillator has R = 10 kOhm and C = 0.01 microfarad in each of three identical RC sections. Using f ≈ 1/(2πRC√6), its oscillation frequency is closest to?

  • A65 Hz
  • B650 Hz
  • C6.5 kHz
  • D65 kHz
Report an error
Correct Answer: B. 650 Hz
Explanation: RC = 10^-4 s. Thus f ≈ 1/(2π×10^-4×√6) ≈ 650 Hz.
