Answer:

A Narrow Band Frequency Modulated signal, with f = 10 kHz, La = 100 MHz, Vi = 5kHz is applied to a frequency multiplier with a factor of 3 to convert it to a wide band FM signal, the output of the multiplier has a WBFM with,

a) 2 = 10 kHz, fa = 100 MHz, 44, = 5kHz

b) f = 30 kHz, J. = 300 MHz, 4 = 15kHz

c) S = 30 kHz, fa = 300 MHz, 4/2 = 5kHz

d) f = 10 kHz, La = 300 MHz, 4, = 15kHz
