AM (amplitude modulation) is able to transmit 10 kHz, while FM (frequency modulation) is able to transmit 200 kHz message signal.
In AM, the amplitude of the carrier signal is modulated by the message signal.
This results in a bandwidth of 10 kHz, which means that signals with frequencies up to 5 kHz above and below the carrier frequency can be transmitted.
On the other hand, in FM, the frequency of the carrier signal is modulated by the message signal.
This results in a bandwidth of 200 kHz, which means that signals with frequencies up to 100 kHz above and below the carrier frequency can be transmitted.
It's important to note that the bandwidth of a transmission method directly affects the quality of the transmitted signal. The wider the bandwidth, the higher the quality of the signal.
However, a wider bandwidth also requires more transmission power, which can be costly.
AM is often used for transmitting voice signals over long distances, while FM is used for broadcasting high-fidelity music and other high-quality audio signals.
