Question 10

A high-altitude scientific balloon transmits atmospheric data to a research station using a frequency-modulated (FM) radio link. The FM transmitter operates with a total bandwidth of 0.45 MHz0.45\text{ MHz}0.45 MHz, and the carrier wave has a maximum frequency deviation of 185 kHz185\text{ kHz}185 kHz.

Determine the maximum frequency of the information signal that can be transmitted.
