A 2.5 MHz carrier is modulated by a music signal that has frequency components ranging from 100 Hz to 5 kHz. What is the range of frequencies generated for the upper sideband?
A) 2.5 MHz to 2.505 MHz
B) 2.5001 MHz to 2.505 MHz
C) 2.495 MHz to 2.499 MHz
D) 2.495 MHz to 2.505 MHz

The upper sideband is generated by adding the modulating signal frequencies to the carrier frequency. The range starts from 2.5 MHz + 100 Hz (0.0001 MHz) to 2.5 MHz + 5 kHz (0.005 MHz), which is 2.5001 MHz to 2.505 MHz.
