Question 294

What determines the frequency of an LC oscillator?

  1. The number of stages in the counter
  2. The number of stages in the divider
  3. The inductance and capacitance in the tank circuitBonne réponse
  4. The time delay of the lag circuit

Explication

An LC oscillator runs at the resonant frequency of its tank, which is set entirely by the inductance and capacitance in that tank. Counters and dividers appear in digital synthesizers, not in what determines an LC tank's resonance.
