A tuned amplifier circuit is used to generate a carrier frequency of ( 2 MHz ) for the amplitude modulation. The value of ( LC ) is

Options

  1. A( 1 2 10⁶ )
  2. B( 1 2 10⁶ )
  3. C( 1 3 10⁶ )
  4. D( 1 4 10⁶ )

Correct answer

D. ( 1 4 10⁶ )

Step-by-step solution

We know ( f= 1 2 L C ) ( L C= 1 2 f ) Given ( f=2 MHz =2 10⁶ ~Hz ) Therefore, ( L C = 1 2 2 10⁶ = 1 4 10⁶ )
