Question

What will be the clapp oscillator frequency if the C1, C2, C3 of clap oscillator is 1μF, 1μF, 2μF respectively and inductance is 1μH?

(a) 0.1MHz

(b) 0.4MHz

(c) 1MHz

(d) 4MHz

I had been asked this question by my school teacher while I was bunking the class.

My doubt is from Clapp Oscillator in section Oscillators of Analog Circuits

Answer 1

Right answer is (b) 0.4MHz

Explanation: Frequency of clap oscillator is  = 3.9 x 10^5  ie approximately 0.4MHz.

Therefore, frequency is equal to .
