Which of the below are true regarding diffe An AM upper sideband (AM-USB) modulator (which blocks the upper sideband of the AM-SC modulated signal before transmission) requires half the channel bandwidth required by AM-SC. 0 O AM suppressed carrier (AM-SC), also known as AM double sideband (AM-DSB), requires half the channel bandwidth required by full AM (or AM with large carrier, AM- LC). Single sideband AM (AM-SSB) requires half the channel bandwidth required by an AM double sideband (AM-DSB) scheme. AM suppressed carrier (AM-SC), also known as AM double sideband (AM-DSB), requires half the channel bandwidth required by an AM single sideband (AM-SSB) scheme. The most power-efficient AM scheme is the full AM, also known as AM with large carrier (AM-LC), which adds the carrier waveform to the modulated signal so as to simplify demodulation. AM suppressed carrier (AM-SC), also known as AM double sideband (AM-DSB), is more power efficient than full AM (as full AM also transmits the carrier signal); however, AM-SC requires a coherent receiver which is a more complex receiver compared to a full AM receiver.
