the highesthe highest modulation frequency used in AM broadcast system ist modulation frequency used in AM broadcast system is
Answers
Explanation:
This varies from country to country. The regulations in the US, Canada, and (possibly) Mexico specify 10 kHz. This means that adjacent stations on the dial overlap, and at night there is interference.
In some countries where broadcasting is poorly regulated, it is likely that some stations are operating without any audio filtering ahead of the transmitter. This would be capable of producing even more adjacent channel interference than that heard in North America.
Most AM receivers are designed to not reproduce high frequencies. This is an interference mitigation strategy. In the US, there are broadcast engineers and even entire radio broadcasting companies that have voluntarily been restricting the bandwidth of their AM stations to 5 or 6 kHz because on “average” radios, no improvement in sound quality is gained by transmitting the full 10 kHz allowed by law.
