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, the half-power point is also known as half-power bandwidth and is a commonly used definition for the cutoff frequency. In the … 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 dropped by half. A bandpass amplifier will have two half-power points, while a See more In antennas, the expression half-power point does not relate to frequency: instead, it describes the extent in space of an antenna beam. The … See more • Antenna aperture • Angular resolution • Full width at half maximum See more WebThe half power bandwidth method is used on the spectrum and works well when you have well separated resonance frequencies. How to extract damping, Eta, or Q-factor (1/Eta) is described here.

WebBandwidth in terms of Q and resonant frequency: BW = f c /Q Where f c = resonant frequency Q = quality factor. A high Q resonant circuit has a narrow bandwidth as compared to a low Q. Bandwidth is measured between the 0.707 current amplitude points. The 0.707 current points correspond to the half power points since P = I 2 R, (0.707) 2 = (0.5). http://www.vibrationdata.com/tutorials2/half_power_bandwidth.pdf bank india indonesia
