What is a typical carrier frequency for amplitude modulation? In particular, for amplitude modulation in spectroscopy.
A typical carrier frequency for amplitude modulation is around 500 kHz to 1600 kHz for AM radio broadcasting. However, this can vary depending on the specific application and regulations in different countries.
The carrier frequency for amplitude modulation is typically chosen based on the available frequency spectrum and the desired coverage area. It is important to select a frequency that is not already being used by another station to avoid interference.
In amplitude modulation, the carrier frequency is modulated by the amplitude of the modulating signal. This results in the carrier wave "carrying" the information of the modulating signal, which can then be demodulated at the receiver to retrieve the original signal.
The choice of carrier frequency can have a significant impact on the quality of the transmitted signal in amplitude modulation. If the frequency is too high, it can result in poor reception due to atmospheric and other interference. If it is too low, the signal may not have enough bandwidth to transmit all of the desired information.
Yes, there are limitations to the carrier frequency in amplitude modulation. In addition to potential interference and bandwidth limitations, there are also regulatory restrictions on the use of certain frequencies for broadcasting. It is important to adhere to these regulations to ensure proper and legal use of the spectrum.
