Question
Compute the LC product of a tuned amplifier circuit required to generate a carrier wave of 1 MHz for amplitude modulation.
Advertisements
Solution
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` = 2.5 × 10–14s
