Compute `LC` product of a tuned amplifer circuit required to generate a carrier `wave` of `1 MHz` for amplitude modulationA. `1.5xx10^(-14)s`B. `1.2xx10^(-12)s`C. `3.2xx10^(-12)s`D. `2.5xx10^(-14) s` |

Answer» Correct Answer - D Frequency of tuned amplifier is `v=(1)/( 2pisqrt(LC))` As per question, `v=1 MHz=10^(6)Hz` or `10^(6)=(1)/(2pisqrt(LC))` or `LC=(1)/(4pi^(2)(10^(6))^(2))=2.5xx10^(-14)s` |
