Vedclass · Answer

(D) The resonant frequency $ f $ of a tuned amplifier circuit ($LC$ circuit) is given by the formula: $ f = \frac{1}{2 \pi \sqrt{LC}} $.Rearranging the formula to solve for $ \sqrt{LC} $,we get: $ \sqrt{LC} = \frac{1}{2 \pi f} $.Given the carrier frequency $ f = 2 	ext{ MHz} = 2 	imes 10^{6} 	ext{ Hz} $.Substituting the value of $ f $ into the equation: $ \sqrt{LC} = \frac{1}{2 \pi 	imes (2 	imes 10^{6})} $.Calculating the denominator: $ \sqrt{LC} = \frac{1}{4 \pi 	imes 10^{6}} $.

$A$ tuned amplifier circuit is used to generate a carrier frequency of $ 2 \text{ MHz} $ for amplitude modulation. The value of $ \sqrt{LC} $ is
