A) \[999.7\text{ }kHz,\text{ }100.3\text{ }kHz,\text{ }999.2\text{ }kHz\]
B) \[1000.8\text{ }kHz,\text{ }998\text{ }kHz,\text{ }1002\text{ }kHz\]
C) \[1002.8\text{ }kHz,\text{ }996\text{ }kHz,\text{ }1106\text{ }kHz\]
D) both (a) and (b)
Correct Answer: D
Solution :
[d] Frequencies present in the output \[=100\,\pm \,0.3\] \[1000\,\pm \,21\,i.e.\to \] \[999.7\text{ }KHz,\text{ }100.3\text{ }KHz,\text{ }999.2\text{ }KHz\] \[1000.8\text{ }KHz,\text{ }998\text{ }KHz,\text{ }1002\text{ }KHz\]
