Electrical Engineering (EE) Question
A Wien-bridge is used to measure the frequency of the input signal. However, the input signal has 10% third harmonic distortion. Specifically the signal is 2 sin 400 πt + 0.2 sin 1200 πt (with t insec). With this input the balance will
  • a)
    Lead to a null indication and setting will correspond to a frequency of 200 Hz
  • b)
    Lead to a null indication and setting will correspond to 260 Hz
  • c)
    Lead to a null indication and setting will correspond to 400 Hz
  • d)
    Not lead to null indication
Correct answer is option 'D'. Can you explain this answer?
