Bandwidth in Amplitude Modulation - Numerical
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:
a.) 900 KHz, 888KHz, 12 KHz
b.) 894 KHz, 884 KHz, 12 KHz
c.) 894 KHz, 888 KHz, 6 KHz
d.) 900 KHz, 888 KHz, 6 KHz
Correct Answer: a) 900 KHz, 888KHz, 12 KHz
Explanation:
Maximum Frequency fUSB = 894 + 6 = 900 kHz
Minimum Frequency fLSB = 894 - 6 = 888 kHz
Bandwidth BW = fUSB fLSB = 900 888 = 12 kHz OR = 2(6 kHz) = 12 kHz
