The amount of frequency deviation in FM signal depends on a. Amplitude of the modulating signal b. Carrier frequency c. Modulating frequency d. Transmitter amplifier

Answer»

a. Amplitude of the modulating signal 

12.

What is the value of carrier frequency in the following equation for the FM signal? v(t)= 5 cos(6600t+ 12sin2500t) a. 1150 Hz b. 6600 Hz c. 2500 Hzd. 1050 Hz

Answer»

d. 1050 Hz

A standard FM signal is represented by

v(t) = Ac cos(2πfct + kfsin2πfmt)

Ac = carrier amplitude

fc = carrier frequency 

kf = modulation index 

fm = modulating frequency 

kf = frequency deviation/modulating frequency 

therefore, fc = 6600/2π = 1050Hz

13.

Answer»

b. 75KHz, 200Khz 

15.

Calculate the maximum frequency deviation for the FM signal v(t) = 10 cos (6000t+ 5sin2200t) a. 2200 Hz b. 6000 Hz c. 1750 Hz d. 11000 Hz

Answer»

c. 1750 Hz 

A standard FM signal is represented by

v(t) = Ac cos(2πfct + kfsin2πfmt)

Ac = carrier amplitude

fc = carrier frequency

kf = modulation index

fm = modulating frequency = 2200/2π = 350 Hz

kf = frequency deviation/modulating frequency

5 = freq deviation/ 350

Therefore, deviation = 5 * 350

= 1750Hz
