Compute `LC` product of a tuned amplifer circuit required to generate a carrier `wave` of `1 MHz` for amplitude modulationA. `2.5xx10^(-14) s`B. `3xx10^(-14) s`C. `1.5xx10^(-14) s`D. `2xx10^(-14) s` |

Answer» Correct Answer - A Frequency of the carrier wave = 1MHz = `10^6` Hz For tuned amplifier , the frequency f is `f=1/(2pisqrt(LC)) =10^6 therefore sqrt(LC)=1/(2pixx10^6)` `therefore LC = 1/(4pi^2xx10^12) =1/(4xx10xx10^12)` `=2.5xx10^(-14) s` (Take `pi^2`=10 ) |
