The frequencies of the two sidebands = 640 kHz , 660 kHz
The frequency of the carrier = (640+660)/2 = 650 kHz.
The frequency of the modulating signal or data = (660-640)/2 = 10 kHz.
Bandwidth required for amplitude modulation = 2 * 10 kHz = 20 kHz
The frequency of the carrier = (640+660)/2 = 650 kHz.
The frequency of the modulating signal or data = (660-640)/2 = 10 kHz.
Bandwidth required for amplitude modulation = 2 * 10 kHz = 20 kHz
