The conventional AM-DSB spectrum consists of
a. Carrier frequency
b. Upper side band frequency
c. Lower side band frequency
d. All of the above
e. Both a and b only.
What is the carrier frequency in an AM wave when its highest
frequency component is 850HZ and the bandwidth of the signal is
50HZ?
80 Hz
625 Hz
695 Hz
825 Hz

An AM broadcast station transmits modulating frequencies up to 6
kHz. If the AM station is transmitting on a frequency of 894 kHz,
the values for maximum and minimum upper and lower sidebands
and the total bandwidth occupied by the AM station are:
900 KHz, 888 KHz, 12 KHz
894 KHz, 884 KHz, 12 KHz
894 KHz, 888 KHz, 6 KHz
900 KHz, 888 KHz, 6 KHz
A modulation index of 0.5 would be same as
5% of Modulation Depth
5 of Modulation Depth
0.5% of Modulation Depth
50% of Modulation Depth
