Two signals of 2GHz and 4GHz are frequency modulated on same carrier 10 GHz. Find the ratio of frequency deviation if band widths of both are equal.

A) 1:2 B) 2:1 C) 1:1 D) 1:4

Your Answer

1:1 because according to relation frequency deviation=K.Vm.fc in this relationship fc is same and K (bolzth man constant) constant so frq deviation depends only on amplitude of the msg signals hence no deviation due to carrier frq
