An Oscillator For An Am Transmitter Has A 100μh Coil And A 10nf Capa

1.	An Oscillator For An Am Transmitter Has A 100μh Coil And A 10nf Capacitor. If A Modulating Frequency Of 10 Khz Modulates The Oscillator, Find The Frequency Range Of The Side Bands?
Answer» Carrier frequency fc = 1/2Π√LC = 1/ 2Π√100 * 10 - 6 * 10 * 10-9 = 1/2Π * 10-6 = 1.59 * 105 Hz = 159 KHz The modulating frequency fm is 10KHZ Therefore the range of AM spectrum is given by (fc fm ) to (fc + fm ) = (159 - 10) to (159 + 10) = 149 KHz to 169 KHz Carrier frequency fc = 1/2Π√LC = 1/ 2Π√100 * 10 - 6 * 10 * 10-9 = 1/2Π * 10-6 = 1.59 * 105 Hz = 159 KHz The modulating frequency fm is 10KHz Therefore the range of AM spectrum is given by (fc fm ) to (fc + fm ) = (159 - 10) to (159 + 10) = 149 KHz to 169 KHz

Answer»

Carrier frequency fc = 1/2Π√LC
= 1/ 2Π√100 * 10 - 6 * 10 * 10-9
= 1/2Π * 10-6
= 1.59 * 105 Hz
= 159 KHz

The modulating frequency fm is 10KHZ

Therefore the range of AM spectrum is given by (fc fm ) to (fc + fm )

= (159 - 10) to (159 + 10)
= 149 KHz to 169 KHz

Carrier frequency fc = 1/2Π√LC
= 1/ 2Π√100 * 10 - 6 * 10 * 10-9
= 1/2Π * 10-6
= 1.59 * 105 Hz
= 159 KHz

The modulating frequency fm is 10KHz

Therefore the range of AM spectrum is given by (fc fm ) to (fc + fm )

= (159 - 10) to (159 + 10)
= 149 KHz to 169 KHz
