Question 46 of 49
Calculate the operating frequency of the following oscillator circuit, if C1 = 0.027 μF and L1 = 105 mH:
Reveal answerf = 2.989 kHz
Notes:Note to your students that the following formula (used to obtain the answer shown) is valid only if the tank circuit’s Q factor is high (at least 10 is the rule-of-thumb):
$$f = \frac{1}{2\pi \sqrt{LC}}$$

Reveal answerf = 18.38 kHz
Notes:Note to your students that the following formula (used to obtain the answer shown) is valid only if the tank circuit’s Q factor is high (at least 10 is the rule-of-thumb):
$$f = \frac{1}{2\pi \sqrt{LC}}$$
