Suppressed carrier single sideband amplitude modulation - SCSSBAM.
depends on type of modulation and other variables
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 Amplitude Modulation (AM), specifically in the case of Double Sideband Suppressed Carrier (DSB-SC) or Full Carrier (DSB-FC) AM, the required bandwidth is twice the bandwidth of the modulating signal. If the modulating signal has a bandwidth of B Hz, the bandwidth required for AM would be 2B Hz. This is because both the upper and lower sidebands of the carrier wave are utilized in the modulation process, each consuming bandwidth equivalent to the original signal.
probably (the carrier frequency +- the maximum frequency of the pulse train)/(the carrier frequency) but pulses have a lot of harmonics
I think it is Frequency Modulation with Phase modulation which it the most bandwidth efficient

Suppressed carrier single sideband amplitude modulation - SCSSBAM.
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.

Increase the bandwidth.
IF we use frequency modulation for transmitting video signal this can cause phase shifting .and eyes can percieve this distortion effect easly . and requires more bandwidth to send the signal .Color levels are adjusted by amplitude in TV .So it s more logic to use Amplitude modulation .
Multi-carrier modulation (MCM) is a method of transmitting data by splitting it into several components, and sending each of these components over separate carrier signals. The individual carriers have narrow bandwidth , but the composite signal can have broad bandwidth.
