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, 888 KHz, 12 KHz
B. 894 KHz, 884 KHz, 12 KHz
C. 894 KHz, 888 KHz, 6 KHz
D. 900 KHz, 888 KHz, 6 KHz
Answer:A
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, 888 KHz, 12 KHz B. 894 KHz, 884 KHz, 12 KHz C. 894 KHz, 888 KHz, 6 KHz D. 900 KHz, 888 KHz, 6 KHz
Explanation: Maximum Frequency fUSB = 894 + 6 = 900 kHz
