In the characterization of antennas the half-power point is also known as half-power beamwidth and relates to measurement position as an angle and describes directionality. The bandwidth of a filter or amplifier is usually defined as the difference between the lower and upper half-power points. This is, therefore, also known as the 3 dB bandwidth. There is no lower half-power point for a low-pass amplifier, so the bandwidth is measured relative to DC, i.

For broader coverage of this topic, see Beam width. In antennas, the expression half-power point does not relate to frequency: instead, it describes the extent in space of an antenna beam. Beamwidth is usually but not always expressed in degrees and for the horizontal plane. It refers to the main lobe, when referenced to the peak effective radiated power of the main lobe. The beamwidth can be computed for arbitrary antenna arrays. In practice there is no high-pass with infinite bandwidth.

All high-passes are bandpasses, but, if properly designed, with the upper half-point so high that it does not affect the application. Classical and Modern Direction-of-Arrival Estimation”, Academic Press, 2009. The time needed by an athlete to complete a 70. 3 distance event varies from race to race and can be influenced by external factors.

These factors include the terrain and the total elevation gained and lost on the course, weather conditions, and course conditions. Finish times range from sub-four-hour completion times by elite level athletes to the imposed race cut off, which is commonly 8 hours and 30 minutes after the start time. 3 World Championship can be obtained through the Ironman 70. 3 series of events held during the 12-month qualification period prior to the championship.
