band of error

band of error

An area either side of a position line within which, for a stated level of probability, the true position is considered located. Fifty and 70% bands are most normally considered bands.
bandwidth
i. The range of frequencies, above and/or below the frequency of a carrier wave, required for modulation of a signal. It is the width of the transmitted frequency spectrum (the difference between the highest and the lowest frequency) of a modulated signal.
ii. A band of error, usually expressed in nautical miles on each side of the position line on the track. See band of error.
iii. The range of frequencies between which an aerial performs to the specified standard.
iv. The space in the frequency domain occupied by signals of a specified nature (e.g., radar, TV).
The number of cycles per second between the limits of a frequency band.
vi. In information theory, the information-carrying capacity of a communications channel.
