A 1000 KHz carrier is modulated with 300 Hz, 8000 Hz and 2 KHz waves.

1.	A 1000 KHz carrier is modulated with 300 Hz, 8000 Hz and 2 KHz waves. Determine the frequencies whose chances of occurring in output is least?(a) 1000 KHz(b) 1002 KHz(c) 998 KHz(d) 999.2 KHzI had been asked this question by my college director while I was bunking the class.The query is from Problems of AM topic in division Amplitude Modulation of Analog Communications
Answer» The CORRECT answer is (a) 1000 KHz Best EXPLANATION: Frequencies present in output are of the form FC ± fm, fc ± 2fm, fc ± 3fm. And 1000 KHz is a MULTIPLE of NONE in the range. Whereas, rest options are one of the multiples in the range.
