sideband การใช้

• LSB / USB : That stands for lower sideband, upper sideband.
• LSB / USB : That stands for lower sideband, upper sideband.
• This mode of transmission is called reduced-carrier single-sideband.
• The phonon transition contributions from all lattice modes constitute the phonon sideband.
• This is a necessary requirement for resolved sideband cooling to work efficiently.
• At levels below 100 % modulation, the sideband structure appears quite asymmetric.
• 8VSB is an 8-level vestigial sideband modulation.
• Here, the motional sideband lies within the peak of the cavity resonance.
• The engineering compromise is vestigial-sideband transmission.
• This prevents the sideband power generated by two stations from interfering with each other.
• Alternatively, the signals could be separated using a demodulator in single sideband mode.
• Telex systems were adapted to short-wave radio by sending tones over single sideband.
• Propagation speeds ( celerities ) are fastest in the ionosphere at the lowest sideband frequency.
• Examples of that are the cooling of ions and the Raman sideband cooling of atoms.
• By 1934, there were several ham stations on the air using single-sideband.
• This can be accomplished by transmitting single-sideband with a normal or slightly reduced carrier.
• For further reading, see sideband.
• :: Ah but imagine the fm spectrum : each sideband a has amplitude and phase.
• Single sideband transmission is a form of amplitude modulation but in effect filters the result of modulation.
• Pirates operating on shortwave from North America often use single sideband modulation as an alternative to AM.
