Necessary Bandwidth
  • For a given class of emission, the width of the frequency band which is just sufficient to ensure the transmission of information at the rate and with the quality required under specified conditions. (RR) Note: Emissions useful for the adequate functioning of the receiving equipment, e. g. , the emission corresponding to the carrier of reduced carrier systems, must be included in the necessary bandwidth. (See Annex J of NTIA Manual of Regulations and Procedures for Federal Radio Frequency Management for formulas used to calculate necessary bandwidth. ) See also bandwidth, bandwidth compression, carrier (cxr), frequency, nominal bandwidth, occupied bandwidth, spurious emission, spurious response, suppressed carrier transmission.
