Frequency Modulation (FM) requires higher bandwidth than Amplitude Modulation (AM) due to the nature of how each modulation method encodes information. FM varies the frequency of the carrier wave to transmit information, which results in a wider range of frequencies being occupied. In contrast, AM varies the amplitude of the carrier wave, which occupies a narrower bandwidth. As a result, FM typically requires about 10 times more bandwidth than AM to accommodate the greater frequency deviations used in the modulation process.

Neither.baseband refers to the original voice signal itselfbroadband refers to a form of wide bandwidth data transmission (e.g. internet traffic)the modulated voice signal consists of a carrier frequency and two sidebands, the bandwidth of the sidebands varies depending on the form of modulation used as well as the bandwidth of the original baseband signal, to reduce transmission power it is possible to eliminate the carrier frequency and to reduce overall bandwidth one of the sidebands may be partially suppressed or eliminated completely (but one sideband must always be fully retained)
In Frequency Modulation (FM), bandwidth is allocated based on the modulation index, which is determined by the frequency deviation of the carrier signal and the frequency of the modulating signal. According to Carson's Rule, the total FM bandwidth is approximately twice the sum of the maximum frequency deviation and the maximum frequency of the modulating signal. This means that FM signals can occupy a wider bandwidth compared to Amplitude Modulation (AM), allowing for better noise immunity and audio quality. Typically, for standard FM broadcasting, the bandwidth is around 200 kHz.
I think it is Frequency Modulation with Phase modulation which it the most bandwidth efficient

if we need simple transmitter and receiver, if we need low bandwidth
AM (Amplitude Modulation) has a smaller bandwidth and can have more stations available in any frequency range. AM is cheaper and can be transmitted over long distances. FM (Frequency Modulation) signals are prone to interference due to physical obstructions. The better sound quality is due to a much higher bandwidth, using FM.

Key features that affect channel capacity include bandwidth, signal-to-noise ratio, and modulation technique. A wider bandwidth allows for more data to be transmitted, while a high signal-to-noise ratio enables better accuracy in data transmission. The modulation technique used can also impact channel capacity by determining how efficiently the available bandwidth is utilized.
To find the bandwidth of a 1066 MHz signal, you first need to understand that bandwidth refers to the range of frequencies a signal occupies. If you have a specific signal operating at 1066 MHz, its bandwidth can be determined by analyzing its modulation scheme or the specifications provided by the manufacturer. For example, if it's a data bus with a specific modulation technique, you may find the bandwidth in the technical documentation. Generally, the bandwidth is the difference between the upper and lower frequency limits related to the signal.
