In a certain oscillator Av = 50. The attention of the feedback circuit must be___________?
Correct answer: D. 02
- A. 1
- B. 01
- C. 10
- D. 02
Explanation
For sustained oscillation, the Barkhausen magnitude condition is A_vβ = 1, so β = 1/A_v = 1/50 = 0.02. The stated 'attention' is a typo for attenuation or feedback fraction.
