Half power point formula
In antennas, the expression half-power point does not relate to frequency: instead, it describes the extent in space of an antenna beam. The half-power point is the angle off boresight at which the antenna gain first falls to half power (approximately -3 dB) from the peak. The angle between the -3 dB points is … See more The half-power point is the point at which the output power has dropped to half of its peak value; that is, at a level of approximately -3 dB. In filters, optical filters, and electronic amplifiers, … See more This occurs when the output voltage has dropped to $${\displaystyle 1/{\sqrt {2}}}$$ (~0.707) of the maximum output voltage and the power has … See more • Antenna aperture • Angular resolution • Full width at half maximum See more WebNov 27, 2024 · I am trying to get damping ratio from a Frequency response plot. I have used a peakfind to get the peaks and return the natural frequewncies and have plotted the half power line onto my original frf plot but cannot get the band width where the lines intersect. i have tried polyfit and interpl but these are not working. Thanks.
